If (H(t)=32+2t), what is (H(10))?
Answer and explanation
Correct answer: 52
Given H(t)=32+2t, substitute 10 for t: H(10)=32+2(10)=32+20=52. Therefore, 52 is the correct answer. The value 42 would result from adding 10 to 32 and incorrectly missing the multiplication 2×10. Exam tip: To evaluate a function, replace the variable with the given value and then perform the operations in order.
