Question

HELPPP SOLVE THIS PLEASE ALL OF IT

Answer 1

f = 3

g = -1

h = 6

r = 18

Explanation:

Box 1

f(x) =
`2x^(4)`-
`12x^(3)`+
`16x^(2)`+4x+15 with x = 3

f(3) =
`2(3^(4))` -
`12(3^(3) )` +
`16(3^(2))`+ 4(3) + 15

Reorder

Evaluate

Multiply

3f = 2 x 81 - 12 + 27 +16 x 9 + 12 +15

3f = 162 - 324 + 144 + 12 + 15

3f = 9

3 ÷ 3

f = 3

Box 1

g(x) =
`3x^(3)` -
`16x^(2)` - 7x - 36 with x = 6

g(6) =
`3(6^(3) )` -
`16(6^(2))` - 7(6) - 36

g6 = 3 x 216 - 576 - 42 - 36

g6 = -6

6 ÷ 6

g = -1

Box 2

h(x) =
`5x^(3)` -
`2x^(2)` - 3 with x = -1

h(-1) =
`5(-1^(3) )` -
`2(-1^(2))` -3

h-1 = -5 + 2 -3

h-1 = -6

-1 ÷ - 1

h = -6

Box 2

r(x) =
`4x^(4)` -
`9x^(2)` + 5x - 2 with x = 2

r(2) =
`4(2^(4) )` -
`9(2^(2) )` + 5(2) - 2

r2 = 64 - 36 + 10 - 2

r2 = 36

2 ÷ 2

r = 18
