What is the value of k? with a= 4 and b= -7

The value of k ⇨  

Explanation:

⟺ Substitute a = 4 and b = -7 in the equation.

From

Our new equation is

⟺ Use the formula of finding k value.

⟺ Substitute a = 4 b = 3 and c = -7 in the formula. (Arranged Expression)

If you are curious where k-value/term comes form, it comes from this equation.

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
