Answer:
<h2>$60.</h2>
Step-by-step explanation:
The cost for 0 cubic yards of gravel refers to the y-intercept of the function.
First, we find the constant ratio of change

The constant ratio of change is 32, that means the cost per cubic yard of gravel is $32.
Now, we just subtract this ratio twice to find the relations until we have x = 0.

So, for 1 cubic yard, the cost is $92.

For 0 cubic yards, the cost is $60, that's the y-intercept or the initial condition.
Therefore, the answer is $60.

Answer:
d) x-intercept
Step-by-step explanation:
The zeros of a function are the values of x that make y = 0.
Thus, they are the points where the graph crosses the x-axis, that is, the x-intercepts.
a) is wrong. the y-intercept is simply the value of y when x = 0.
b) and c) are wrong. A quadratic can have only one maximum or one minimum; it can't have both. And they are not zeros except in the special case of y = ±ax².
The diagram below is the graph of y = x² + 3x - 46. It shows the zeros at x = -23 and x = 20. The minimum and the y-intercept are not zeros of the function.
