[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
