Which quadratic function is represented by the graph?

Answer 1

1st option

Explanation:

From the graph the zeros are x = - 3 and x = 1 , then the corresponding factors are

(x + 3) and (x - 1) , so

y = a(x + 3)(x - 1) ← a is a multiplier

To find a substitute a point on the graph into the equation

Using (0, - 1.5 ) , then

- 1.5 = a(3)(- 1) = - 3a ( divide both sides by - 3 )

0.5 = a

Then

f(x) = 0.5(x + 3)(x - 1)
