Lesson Summary Linear functions are graphed as straight lines while exponential functions are curved. Linear functions are typically in the form y = mx + b, which is used to discover the slope, or simply the change in y divided by the change in x, while exponential functions are typically in the form y = (1 + r) x.

A quadratic function in the variable x is defined by an equation that is a polynomial of degree 2 in x. That is, it is defined by an equation of the form y = ax^2 +bx + c, where a, b, and c are constants. ... By contrast, an exponential function in x is defined by an equation of the form y = ab^x + c.

There is a big difference between an exponential function and a polynomial. The function p(x) = x3 is a polynomial. Here the “variable”, x, is being raised to some constant power. The function f(x)=3x is an exponential function; the variable is the exponent.

Logarithmic functions are the inverses of exponential functions. The inverse of the exponential function y = ax is x = ay. The logarithmic function y = logax is defined to be equivalent to the exponential equation x = ay.

An exponential function is a function where a fixed number is raised to every x. In other words, you pick a number, and each x on the axis is the power that the number is raised to in order to get y.

Thanks. it is a linear equation because the highest order of exponents is equal to 1. the equation is in standard form.

O(n^2) is polynomial time. The polynomial is f(n) = n^2. On the other hand, O(2^n) is exponential time, where the exponential function implied is f(n) = 2^n. The difference is whether the function of n places n in the base of an exponentiation, or in the exponent itself.

The EXP function finds the value of the constant e raised to a given number, so you can think of the EXP function as e^(number), where e ≈ 2.718. The exponential function can be used to get the value of e by passing the number 1 as the argument.

The difference between linear function and arithmetic sequences is that linear function is defined for all values of independent variable of linear function while arithmetic sequence is defined for positive integer values of variable.

The exponential function is its own slope function: the slope of e-to-the-x is e-to-the-x. The inverse of ex is ln x, which is loge x, the natural logarithm of x.

If you see an equation in this form or are given similarly related values then it is. most probably a linear function. y = mx +b. what you have to notice here is the X, if the X has no exponents on it, then it is usually linear, but if the X is X squared or higher then it would not be a linear function.

Exponential functions have the form f(x) = bx, where b > 0 and b ≠ 1. Just as in any exponential expression, b is called the base and x is called the exponent. An example of an exponential function is the growth of bacteria.

The exponential form is usually used if the value of the constant is either too small or too large. ... The only difference between %g and %G is that they will print the "e" of the exponential form in lower case and upper case respectively. It will print in Fractional form when the constant is between .

linear functions have no exponents higher than 1, and a graph that looks like a straight line. non-linear functions have at least one exponent higher than 1, and a graph that isn't a straight line.

The inverse of a logarithmic function is an exponential function. When you graph both the logarithmic function and its inverse, and you also graph the line y = x, you will note that the graphs of the logarithmic function and the exponential function are mirror images of one another with respect to the line y = x.

We can think of an arithmetic sequence as a function on the domain of the natural numbers; it is a linear function because it has a constant rate of change. The common difference is the constant rate of change, or the slope of the function.

Lesson Summary The equation of a linear function has no exponents higher than 1, and the graph of a linear function is a straight line. The equation of a non-linear function has at least one exponent higher than 1, and the graph of a non-linear function is a curved line.
