The table shows several points for function f(x). -4 -2 0 2 4. 6 8 10 f(x) 19 15 11 -6 7 -8 -10 -14 Which statement correctly identifies a point on the graph of f'(x)? The point (4, -7) is on the graph of f(x), so the point (7, 4) will be on the graph of f'(). O The point (-2, 15) is on the graph of f(x), so the point (2, -15) will be on the graph of F"(x). The point (-4, 19) is on the graph of f(x), so the point (-4, -19) will be on the graph of f'(x). The point (10, -14) is on the graph of f(x), so the point (-14, 10) will be on the graph of f'(X). ​

A function rule for the relationship between the amount of plant food remaining, f(x), and the number of days that have passed, x is

Step-by-step explanation:

We are given that Ryan used 72 mL of food over the course of a 6 day study.

So, He used amount per day =

He used amount per day =12 ml/day

Now we are given that t the amount of plant food remaining decreased an equal amount each day, and he used the entire 72 milliliters by the end of his study.

So, The equation becomes : f(x)=72-12x

f(x):The amount of plant food remaining

x : The number of days that have passed

Hence  a function rule for the relationship between the amount of plant food remaining, f(x), and the number of days that have passed, x is
