Question

Given f(x) = -6(4 - x), what is the value of f(-0.6)?

A)-30
B) -27.6
C) -60
D) -24.6

Answer 1

Explanation:

f(x) = -6(4-x) which f(-0.6)

therefore:

we multiple -6×4= -24 and -×- =+ this implies +6×x = 6x

we add:

-24 + 6x which we already know x is = -0.6

-24 + 6 (-0.6)

-24 + 3.6

= the big number always carry the sign

the answer is = -27.6
