The range of a function is the set of all possible outputs.
When the quadratic functions are in standard form, they generally look like this:
If a is positive, the function opens up; if it’s negative, the function opens down. In this form, the y-coordinate of the vertex is found by evaluating f(−). For example, consider this function:
f(x) =
So we’re gonna do: −b/2a=−8/2(−2)=−8/−4=2
Then, we plug this in:
a is negative, so the range is all real numbers less than or equal to 5.

Answer:
2,3,5,6,9,10
Step-by-step explanation:
To do this, we can look at how each value divides into 90. If it produces a whole number, they will be consider to be divisible
This means 4 is the only value that is not divisible into 90
