Question

If f(x) = x^2 and h(x) = 2-x, then hf (-3) =​

Answer 1

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
