Answer:
The equation is -3x^2 + 30x + 225 = 0, and the number of days is 15.
Step-by-step explanation:
I assume an x is missing, and the function is h(x) = -3x^2 + 30x + 225
You want to know the number of days in which the function value is zero.
-3x^2 + 30x + 225 = 0
Divide both sides by -3.
x^2 - 10x - 75 = 0
(x - 15)(x + 5) = 0
x - 15 = 0 or x + 5 = 0
x = 15 or x = -5
We discard the negative solution.
Answer: The equation is -3x^2 + 30x + 225 = 0, and the number of days is 15.

Answer:
Step-by-step explanation:
The blanks you're to fill in explain the steps.
The y-intercept is the value of the function when x=0. It is where the graph crosses the y-axis.
f(0) = a·b^0 = a·1 = a
Reading the y-intercept from the graph, we see ...
The y-intercept is 3. The a-value of the function is 3.
__
The point when x=1 is ...
f(1) = a·b^1 = 3b
Reading the value from the graph, we find the point to be (1, 6). This means ...
3b = 6
b = 2 . . . . . . . divide both sides by 3
The point when x=1 is (1, 6). The b-value of the function is 2.
The equation of the function is f(x) = 3·2^x.
