Question

For this exponential function,what is the output value (y),when the input value (x) is 2?y = 5•2x=(2, [?])

Answer 1

(2, 20)

Step-by-step explanation:

Given the below exponential function;

`y=5\cdot2^x`

Let's go ahead and solve for y when x = 2 by substituting x with 2 in the above function as seen below;

`y=5\cdot2^2=5\cdot4=20`

We can see from the above that when x = 2, y = 20.
