If f(x) = x^2 and h(x) = 2-x, then hf (-3) =
1 answer:
Answer:
hf(-3) = -7
Step-by-step explanation:
f(x) = x²
h(x) = 2 - x
To find hf(x), we will substitute f(x) function as x into the h(x) function.
h(x) = 2 - x
hf(x) = 2 - (x)²
hf(x) = 2 - x²
How that we have the hf(x) function, to find hf(-3), we substitute x = -3 into the new function.
hf(x) = 2 - x²
hf(-3) = 2 - (-3)² = 2 - 9 = -7
