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

$f(5)=121$
