Question

Which two points are on the graph of g(x) = (15)x

Answer 1

The function is g(x) = 15^x.

Given that you did not include the answer choices, I will explain you in detail how to find the point.

First, the points are the ordered pairs (x, g(x)), which means that every point is formed by two coordinates, the first coordinate is the x-value (independent variable) and the second coordinate is the value of the function for that x-value.

Additionally, you must know that 15^x means 15 raised to the power x.

You can give x any real value (from negative infinity to infinity) given that the function 15^x is defined for all the real values.

For example if you choose x = 2, g(x) = g(2) = 15^2 = 15*15 =225, which means that the point (2, 225) is on the graph.

Here you hava a table with some points to reinforce the idea:

x          g(x) = 15^x                                                    point as an 
                                                                                 ordered pair

- 2      g(-2) = 15^(-2 ) = 0.00444                              (-2,0.00444)

-1      g(-1) = 15^(-1) = 0.0667                                  (-1, 0.00667)

0       g(0) = 15^0 = 1                                                (0,1)

2        g(2) = 15^2 = 225                                            (2,225)

10      g(10) - 15^10 = 576,650,390,625                   too big to be written here 
   

Now you know how to find any point of the graph: feed x value in the function g(x).
