The number of horses occupying stalls at the county fairgrounds can be modeled by the following function, where x represents the number of
days since the first of June.
h(x) = -3^2 + 30x + 225
Rewrite this function in the form that reveals the zeros of the function, which is when there are no horses occupying stalls at the fairgrounds.

The equation is -3x^2 + 30x + 225 = 0, and the number of days is 15.

Step-by-step explanation:

Assuming 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.

The equation is -3x^2 + 30x + 225 = 0, and the number of days is 15.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
