Can anyone me with these three plz i have no clue how to do this

Answer for question (42):

We need to find the composition of two functions f(x) and g(x).

By the definition, the composition of two functions is defined as .

That is, The composition of two functions f and g is the new function , by performing g first and then performing f.

Here we have

Now plug in , we get

It is given that , using this we need to find

Replace x by x-1 in f(x),

Now we need to find ,

So

So the soiution is (B): 24

Solution for question (43):

Plug in to find h(-5):

+5(-5)-13 [/tex]

Thus the answer for (43) is (D): 112.

Solution for question (44):

The height of a ball projected into the air can be represented by the function is

Then to find the height of the ball in feet when it has been in the air for 2 seconds:

Plug in t=2 in h(t),

Thus the answer for (44) is (A): 64.

picture below

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
