Math Problem Statement

You are given the functionh(t)=−t2−2t−4Find h(2).

Solution

To find h(2)h(2), substitute t=2t = 2 into the given function h(t)=t22t4h(t) = -t^2 - 2t - 4:

h(2)=(2)22(2)4h(2) = -(2)^2 - 2(2) - 4

Step-by-step solution:

  1. Compute (2)2=4(2)^2 = 4, so: h(2)=42(2)4h(2) = -4 - 2(2) - 4

  2. Compute 2(2)=42(2) = 4, so: h(2)=444h(2) = -4 - 4 - 4

  3. Combine all terms: h(2)=12h(2) = -12

Final Answer:

h(2)=12h(2) = -12
