Question

Find f(h(-1)).
-9
2
11
-11

Answer 1

f(h(-1)) = - 11 or D

Explanation:

h(-1) = -2(-1)^2 - 3(-1) + 1

h(-1) = -2(1) + 3 + 1

h(-1) = 2

f(2) = (2t + 7)/(t - 3)

f(2) = (2*2 + 7) / (2 - 3)

f(2) = 11/-1

f(2) = - 11

Be very careful how you handle this. The way I have done it will work, but it does not work all the time.

The sure way to handle this is to put(h(n)) every place you can on the right side of f(t)

f(h(n)) = (2(h(n) + 7)) / (h(n) - 3)
