Answer:
area of rectangle=(x+4)(x^2+3x+2)
Step-by-step explanation:
area of rectangle=
area of rectangle=
where, length=height=(x+4)
width=(x^2+3x+2)
area of rectangle=(x+4)(x^2+3x+4)
(A): When it asks for a y-intercept, it is basically asking what is the value of y when x=0. In this case, when x=0, y=50. So the y-intercept is 50.
(B): The avg. rate of change is the same as asking for slope. So we want to use slope formula ->
. Using the values in your table -> 
(C) You can generate a linear function with a y-intercept and a slope using the following formula -> y= (average rate of change)*x + y-intercept ->
Then set y=60 and solve for x. Your domain is [0, solved value] with square brackets since you are including the endpoints.
