Question

Evaluate each of the following given the function definition and input values

Answer 1

Question:

Solution:

1) if

`f(x)=x^2-2`

then :

`f(-3)=(-3)^2-2\text{ = 9-2 = 7}`

and

`f(0)=0^2-2\text{ = 0-2 = -2}`

2) if

`g(x)=3x+1`

then

`g(4)=3(4)+1\text{ = 12+1 = 13}`

and

`g(-2)=3(-2)+1\text{ = -6+1 = -5}`

3) if

`h(x)=3^x`

then

`h(3)=3^3=\text{ 3 x 3 x 3 = 27}`

and

`h(-1)=3^(-1)\text{ = }(1)/(3)\text{ = 0.33}`
