Let h(x) = x*2 + kw - 8. If h(-1) = -5, what is the value of h(4)? Help

Alisiya [41]

Answer:

h(4) = 0

Step-by-step explanation:

Hoping its ' kx '

$h(x) = x^2 + kx -8 \\\\h(-1) = (-1)^2 + k(-1) - 8\\\\-5 = 1 - k -8\\\\-5 = -k -7\\\\-5 + 7 = -k\\\\2 = -k\\-2 = k$

Now we have k = -2. We will find h(4).

$h(4) = (4)^2 + (-2)(4) - 8 = 16 -8 - 8 = 0$
