A) f(x) = 0 at x = 1

B) f(0) = 2

C) The increasing interval is [-4, 1] and [2, 3]

D) The y intercept is 1

E) The average rate of change is -5

How to find the values

To solve the problems, let us remember that x is input values and f(x) = y is the output values

A) In this case, we are asked what input value/(x) is required to have an output equal to 0. Hence we look through the column of f(x) and search for 0. At this point, we check the corresponding value of x which is 1

B) Here, we search for x = 0 and find the corresponding value for g(x) which is 2

C) WE investigate the column to ascertain when f(x) is increasing. Increase is noticed from 0 to 30, and 0 to 2. The corresponding values of x at this point is 1 to -4 and 2 to 3. This is written as [-4, 1] and [2, 3]

D) The y intercept is the values of f(x) when x = 0. This is same as in B so the value is 2

E) Average rate of change is calculated by

= change in y) / change in x

= (20 - 0) / (-3 - 1)

= 20 / -4

= -5
