[tex]\huge\boxed{\boxed{9}}[/tex]

Start with the original function:

[tex]f(x)=-4x+1[/tex]

Substitute in the known value:

[tex]f(-2)=-4(-2)+1[/tex]

Multiply:

[tex]f(-2)=8+1[/tex]

Add:

[tex]f(-2)=\large\boxed{9}[/tex]

Answer:

9

Step-by-step explanation:

In this type of equation, x represents the input. So, all you simply have to do is  replace x with -2 and then solve.

Input: -2

f(x) = -4x + 1

f(-2) = -4(-2) + 1

f(-2) = 8 + 1

f(-2) = 9
