Question

If h(x) = 1 2 x4 - 3x3, find h(4)

A)-200   


B)-64  
C)-28
D) -16

Answer 1

-64

Explanation:

`h(x) =(1)/(2)x^4 - 3x^3`

Now we need to find out h(4)

to find h(4), we plug in 4 for x

Replace all x by 4 in h(x) and evaluate h(4)

`h(x) =(1)/(2)x^4 - 3x^3`

`h(4) =(1)/(2)(4)^4 - 3(4)^3`

`h(4) =128- 192=-64`

So the value of f(4)= -64
