Math Problem Statement

Given f(t) = t^2 - t and h(x) = 3x + 8, evaluate h(f(2)).

Solution

We are given two functions: f(t)=t2tf(t) = t^2 - t and h(x)=3x+8h(x) = 3x + 8, and the task is to evaluate h(f(2))h(f(2)).

Step-by-Step Solution:

  1. Evaluate f(2)f(2):

    Using the given function f(t)=t2tf(t) = t^2 - t, substitute t=2t = 2:

    f(2)=222=42=2f(2) = 2^2 - 2 = 4 - 2 = 2

  2. Evaluate h(f(2))h(f(2)):

    Now that we know f(2)=2f(2) = 2, substitute x=2x = 2 into the function h(x)=3x+8h(x) = 3x + 8:

    h(2)=3(2)+8=6+8=14h(2) = 3(2) + 8 = 6 + 8 = 14

Thus, h(f(2))=14h(f(2)) = 14.

Would you like a detailed explanation of any step?

Here are five related questions to extend your understanding:

  1. How would the answer change if f(t)f(t) were t2+tt^2 + t instead of t2tt^2 - t?
  2. Can you find h(f(1))h(f(-1))?
  3. What happens if the functions ff and hh are swapped, and we compute f(h(2))f(h(2))?
  4. What does it mean to compose functions like in this problem?
  5. How would you graph h(f(x))h(f(x))?

Tip: When evaluating compositions of functions, always work from the inside out!
