Answer:
C(-1)= -5
Step-by-step explanation:
This question asks us to find C(-1). We know what C(x) is, it is:
Therefore, we must substitute -1 in for every x to find C(-1).
Now, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
First, evaluate the exponent.
-1^2=-1*-1=1
Next, multiply -4 and 1.
Multiply 4 and -1 again.
Add the numbers together.
