Question

F(x) = -x + 2, find f(-1).

Answer 1

Answer:

3

Step-by-step explanation: make f(x)= y and plug in -x + -1 then add 2

Answer 2

Answer:

3

Step-by-step explanation:

To find what the function of -1 is, we need to plug -1 as x into the equation

f(x) = -x + 2

f (-1) = -[-1] + 2

f (-1) = 1 + 2

f (-1) = 3

{or/also a different format: }

f (x) is the same thing as y

(-1 , 3)

is another way to format the solution
