If f(x)=-4(x-6)+15,What is f(3)?A -3 B 3 C 27 D 51

Answer :

SOLUTION

We want to find f(3), if

[tex]f(x)=-4(x-6)+15[/tex]

To do this, we put x for 3 into the equation, we have

[tex]\begin{gathered} f(3)=-4(3-6)+15 \\ =-4(-3)+15 \\ =12+15 \\ =27 \end{gathered}[/tex]

Hence the answer is 27, option C
