The functions are fx 4x2 gx 3x32 Find f5 g3Solutionfx 4x

The functions are:

f(x) = -4x+2

g(x) = -3x³-2

Find:

f(5)

g(-3)

f(x) = -4x + 2

So, f(5) = -4(5) + 2
f(5) = -20 + 2
f(5) = -18 ----> ANSWER

------------------------------------------

g(x) = -3x^3- 2

So, g(-3) = -3(-3)^3 - 2
g(-3) = -3(-27) - 2
g(-3) = 81 - 2
g(-3) = 79 ----> ANSWER
