Answer:
3
Step-by-step explanation: make f(x)= y and plug in -x + -1 then add 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
