Question

If f(x) = 2x - 3, g(x) = -2x^3 + 2 and h(x) = 3x, then h(2) + f(g(-1)) =

Answer 1

please help

Answer 2

11

Answer 3

how u do?

Answer 4

put x=2 in h(x)=3x to get h(2)

Answer 5

then put x=-1 in g(x) to get g(-1). Subsequently, put the result of g(-1) in place of x in f(x) to get f(g(-1)).


Then add both.
h(2) + f(g(-1))

Answer 6

so h(2)=6

Answer 7

right

Answer 8

f(g(-1)) =?

Answer 9

2(-1)^3 -3 ?

Answer 10

I see 2(-1)^3 +2 =5

Answer 11

so 6+5=11

Answer 12

no it is not right

Answer 13

f(g(-1)) = f (result of g(-1)) = f (-2 *-1^3 +2) = f(2 + 2) = f(4) = 2(4)-3 = 5

Answer 14

ah I understand now. Thank you
