Question

If f{x)=-4(x-6)+15,what is f(3)?
A -3 B3 C27 D51

Answer 1

Answer: C) 27

Explanation:

=> f(x) = -4(x - 6) + 15
Therefore, f(3) means x = 3.

Substituting the value of ‘x’ :-
=> -4(x - 6) + 15
= -4(3 - 6) + 15
= -4 * 3 + -4 * -6 + 15 (Opening brackets)
= -12 + 24 + 15
= 12 + 15
= 27

Therefore, f(3) = 27

Answer 2

C. f(3)=27

Explanation:

f(3)=-4(3-6)+15

f(3)=-4(-3)+15

f(3)=12+15

f(3)=27
