Question

If f(x) = х2 + 1 and g(x) = 3х+ 1, find 2-f(4).
o 18
o 34
o
55

Answer 1

-15

Explanation:

The given functions are
`f(x)=x^2+1` and
`g(x)=3x+1`

We want to find
`2-f(4)`

When we substitute x=4 into
`f(x)=x^2+1` we get:

`f(4)=4^2+1`

We evaluate to get:

`f(4)=16+1`

This simplifies to

`f(4)=17`

Therefore
`2-f(4)=2-17=-15`

I am very sure you missed out some important parts of the question because g(x) is not used.
