Answer:

у = x² + 7x - 30

Step-by-step explanation:

x₁ = 3 and x₂ = -10

Use the formula (x - x₁)(x - x₂) = 0

(x - 3)(x - (-10)) = 0

(x - 3)(x + 10) = 0

x² + 10x - 3x - 30 = 0

x² + 7x - 30 = 0

Given f(x) = abx + c. How would increasing the value of a change the graph?

Helen [10]

Increasing the value of a would change the slope of the function specifically it would increase as well. Therefore, the line would be steeper than the original. The term ab represents the slope of the function and changing either one would result to the change of the steepness of the line.
