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.

y=1/4x-4

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
