Answer:
10
Step-by-step explanation:
We are given:
f(x)= -2x+4
and told to find f(x) when x= -3
X is equal to -3, therefore we can substitute -3 in for x.
f(x)= -2x+4 when x= -3
f(-3)= -2(-3)+4
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
First, multiply -2 and -3. Multiplying 2 negative numbers makes a positive number.
f(-3)= 6+4
Add 6 and 4
f(-3)=10
When x= -3, f(x) is 10
