Hello! I need some assistance with this homework question please!

Answer 1

Question:

Solution:

Note that the points x = 0, x=1 and x= 4 belong to the interval -4≤ x ≤4. In this interval, we have that:

`f(x)=4x-3`

thus, we get the following values:

`f(0)=4(0)-3=0-3\text{ = -3}`
`f(1)=4(1)-3=4-3=1`

and

`f(4)=4(4)-3\text{ = 16-3 = 13}`

Now, note that the point x = 5 belongs to the interval 4

`f(x)=x^3-4`

then:

`f(5)=5^3-4=121`

So that, we can conclude that the correct answers are:

`f(0)=\text{ -3}`

`f(1)=1`

`f(4)\text{= 13}`

and

`f(5)=121`
