Question

Using the following function rule F(x) = 5^x + 5, the value of

F(-3) is -120.

True or False​

Answer 1

False

Explanation:

Given F(x) = 5^x + 5

To find value of F(-3)

we will plug -3 in place x

then we have

`F(-3) = 5^x + 5\\=>F(-3) = 5^3 + 5 =>F(-3) = 125 + 5\\=>F(-3) = 120`

we have used
`5^3 = 5*5*5 = 125` in the above solution.

It is given that F(-3) is -120 while we have calculated F(-3) to be 120.

Thus, F(-3) is -120 is false.
