Question

How do you write range on a graph?

Answer 1

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:

$f(x) = ax^{2} + bx + c$

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(−$\frac{b}{2a}$). For example, consider this function:

f(x) = $-2x^{2} + 8x -3$

So we’re gonna do: −b/2a=−8/2(−2)=−8/−4=2

Then, we plug this in:

$f(2) = -2(2)^{2} +8(2) -3 = 5$

a is negative, so the range is all real numbers less than or equal to 5.
