Answer:
f(-2)= -4
Step-by-step explanation:
plug in -2 for every x you see in the equation.
f(-2)= -22-9(-2)
= -22+18
= -4
therefore, f(-2)= -4
Answer:
[tex]\boxed {\tt f(-2)=-4}[/tex]
Step-by-step explanation:
We are given the function:
[tex]f(x)= -22-9x[/tex]
We want to find f(-2). Therefore, we must substitute -2 in for each x.
[tex]f(-2)=-22-9(-2)[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Multiply -9 and -2.
[tex]f(-2)=-22+18[/tex]
Add 18 to -22.
[tex]f(-2)=-4[/tex]
f(-2) is equal to -4 for f(x)=-22-9x
