Answer:

y=-4x^2+9x+9

Step-by-step explanation:

1st: we assume the equation will be in standard form (ax^2+bx+c)

2nd: since the graph passes through (0,9) then the y-intercept is @(0,9) or your c is 9.

3rd: since it passes through (2,11) then 11=4a+2b+c

4th: since it also passes through (3,0) then 0=9a+3b+c

* so we have c=9, 11= 4a+2b+c, and 0= 9a+3b+c*

So a=-4, b=9, c=9

plug in the numbers and you get y= 4x^2+9x+9

Hope this helps you. :3

1. the height of a water bottle in a bathtub, w, is a function of time, t. Let P represent this function. Height is measured in
zhannawk [14.2K]

3. After 10 minutes, the height of the water is 4 inches

Answer:

1) P(20) = 0

2) P(0) = 0

3) P(10) = 4

4) P(4) = 10

Step-by-step explanation:

We are told that the function P(t) denotes the height of the water in the bath tub.

At P(0) = 0, it means that after 0 minutes, there is no water in the bath tub.

1) If after 20 minutes, the bathtub is empty, then we can depict the function as; P(20) = 0

2) The bath tub starts out with no water. It means at 0 minutes, there was no water in the tub. Thus;

P(0) = 0

3) If after 10 minutes, the height of the water is to be 4 inches, then;

P(10) = 4

4) If the height is 10 inches after 4 minutes, then;

P(4) = 10

Step-by-step explanation:

f(h(x))=

f(12/x)=

(12/x)^2+7=

12^2/x^2 + 7=

144/x^2 +7=

144/x^2 +7*x^2/x^2=

144/x^2+7x^2/x^2=(7x^2+144)/x^2
