Pls answer the question above (in the picture) and show your work.

A) The y intercept is (0,-18)

This is true.

The x value x = 0 leads to the y value y = -18. See row 1 of the table. Keep in mind that y = f(x).

==========================

B) The max value of the function is 4

This is false.

The largest y or f(x) value shown is y = 70 which is in the last row of the table. There could be other larger y values, but we dont need to find them as all we need to do is find a counter-example to disprove the initial claim.

==========================

C) A local minimum is located within the interval 3 <= x <= 6

This is true.

When we go from x = 3 to x = 6, the function decreases for a bit, then it starts to increase. This change from decreasing to increasing means that the function bottoms out somewhere forming a valley, ie a local min.

Visually, it might help to plot the points as shown in the attached image below. We see that the local min could be around point F somewhere or perhaps point F itself is the local min.

==========================

D) A local max is in the interval 1 <= x <= 3

This is true.

This is similar to part C above, but now we're looking to see if we transition from increasing to decreasing. In this case this happens. So somewhere in the interval from x = 1 to x = 3 is a local max point.

Visually the point C could be the local max (see attached image below) as this is one potential spot where the function curve reaches its highest peak in this very specific region/interval. Some math books will use the term "neighborhood" in place of "interval" and it means effectively the same thing.

==========================

E) The function is increasing on the interval 6 <= x <= 8

This is true.

Refer to the graph below. Note how the points go up as we move from left to right. In other words, the y values are increasing as we increase the x values from x = 6 to x = 8.

============================================

There are 4 true answers and they are: choice A, choice C, choice D, choice E

A shorter way to say this is to say "only choice B is false while the rest are true".

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
