Answer:

A: *Graph shown in image*

B: She will reach her goal when the x is 14 (14,460) with y being 460 (or the goal) giving you the equation y = \frac{50}{2} x + 110 going up 50 and going right 2 with x being 7 meaning you would have to go up 50 and right 2, seven times to reach 460.

Step-by-step explanation:

A: From your previous question you asked 14 hours ago with a screenshot, you did your graph wrong so for YOU make your graph look like the second image. (Plot the point 0,110 for the y intercept and plot -4.4,0 for the x line)

B: Lot's of explaining but you will get it once you add it to your own graph and go with the flow. Kind of like slope intercept form.

For C: you can answer in your own words since I gave you the priority answer(s)

Hellooo please i need help on these question

( f - g )(x) = 10x - 17 and ( f ° g)(-6)  = 60. The answers are option D and B

<h3>There are different type of Function</h3>

Different types of function demands different ways of solving them. Different types are simple function, function by substitution and function of function.

Given that

f(x) = x^{2} + 9x - 14 and g(x) = x^{2} - x + 3

( f - g )(x) will be the difference between f(x) and g(x)

( f - g )(x) = x^{2} + 9x - 14 - ( x^{2} - x + 3)

( f - g )(x) =  x^{2} + 9x - 14 -  x^{2} + x - 3

( f - g )(x) = 10x - 17

Also, if f(x) = 3x^{2} - 15 and g(x) = 1 - 2/3 x

( f ° g)(-6) means that we will evaluate g at -6, then evaluate f at the result of g(-6)

g(-6) = 1 - 2/3 (-6)

g(-6) = 1 + 4

g(-6) = 5

f(g(-6)) = 3(5^{2}) - 15

f(g(-6)) = 3 x 25 - 15

f(g(-6)) = 75 - 15

f(g(-6)) = 60

Therefore, ( f - g )(x) = 10x - 17 and ( f ° g)(-6)  = 60
