Answer:
It only counts as a zero when the y-intercept is (0,0).
Step-by-step explanation:
The zeros of a quadratic function are always written as (x,0), while the y-intercept is always written as (0,y). Therefore, in order for a y-intercept to be a zero, it must be (0,0), because the y-coordinate in any zero is 0. At any other time, the y-intercept is not a zero.
Answer:
(5, -9).
Step-by-step explanation:
The vertex if (h, k).
So for 6(x - 5)^2 - 9 the vertex is the point (5, -9).
Answer:

Step-by-step explanation:
x is how many years
Answer:
<h2>f(4) = -4</h2>
Step-by-step explanation:
f(x) = 4x - 20
f(4) → put x = 4 to the equation of the function:
f(4) = 4(4) - 20 = 16 - 20 = -4
The second answer is the correct answer
