Question

Evaluate the function rule below when x= -2

f(x)=-x+2

Answer 1

f(- 2) = 4

Explanation:

substitute x = - 2 into f(x) , then

f(- 2) = - (- 2) + 2 = 2 + 2 = 4

Answer 2

Given function:
`f(x)=-x+2`

To evaluate the function when
`x=-2`, substitute the given value for
`x` into the function and solve:

`\implies f(-2)=-(-2)+2`

`\implies f(-2)=2+2`

`\implies f(-2)=4`
