Answer:
f(-1) = 121
Step-by-step explanation:
f(x) = (5-6x)^2 (First we will substitute x for -1)
f(-1) = (5-6(-1))^2 (Then we will combine like terms)
f(-1) = (11)^2 (Then we will square it)
f(-1) = 121 (You are done)
Answer:
Frankly, substitution is almost always a better method. Graphing is a very precise and time consuming process where you have to calculate several..
