If (B(h)=96-6h), what is the value of (B(h)) at (h=4)?
Answer and explanation
Correct answer: 72
Given \(B(h)=96-6h\). Substituting \(h=4\), we get \(B(4)=96-6(4)=96-24=72\). Therefore, 72 is correct. The value 24 is only \(6\times4\); it still needs to be subtracted from 96. Exam tip: To evaluate a function, substitute the given value for the variable and then follow the order of operations.
