Quadratic function
i need writing quadratic functions the zeroes are 3 and -10

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

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
