Question

Evaluate the function add to give them values of the independent variable and simplify

Answer 1

Given function,

`h(x)=x^4+2x^2-5`

a.h(3)

`h^{}(3)=3^4+2*3^2-5=81+18-5=94`

b.h(-1)

`h(-1)=(-1)^4+2(-1)^2-5=1+2-5=-2`

c.h(-x)

`h(-x)=(-x)^4+2(-x)^2-5=x^4+2x-5`

d.h(3a)

`h(3a)=(3a)^4+2(3a)^2-5=81a^4+18a^2-5`
