Question

Graph the exponential function.
y = 5(2)x
(1 point)

Answer 1

There are multiple ways to graph the exponential function, but one common method is to create a table of values and plot the points.

Choose a few values for x and calculate the corresponding y values:

When x = -2, y = 5(2)^-2 = 5(1/4) = 5/4
When x = -1, y = 5(2)^-1 = 5(1/2) = 5/2
When x = 0, y = 5(2)^0 = 5(1) = 5
When x = 1, y = 5(2)^1 = 5(2) = 10
When x = 2, y = 5(2)^2 = 5(4) = 20

Plot the points (-2, 5/4), (-1, 5/2), (0, 5), (1, 10), and (2, 20) on a graph.
