Question

18. Determine the x-intercepts zeros) of the function below given in factored form, and then plot their points.You don't need to graph the entire parabola of the quadratic function. (2 points)y = (x - 4)(x + 3)

Answer 1

Answer:

The x-intercepts = (-3, 0) and (4, 0)

The graph of the equation showing the x-intercepts is plotted below

Step-by-step explanation:

The given quadratic function is:

y = (x - 4)(x + 3)

To find the x-intercepts of the function, set y = 0

(x - 4)(x + 3) = 0

Equate each of the factors to zero

x - 4 = 0

x = 4

x + 3 = 0

x = -3

Therefore, the x-intercepts of the quadratic function are:

(-3, 0) and (4, 0)

The graph of the parabola indicating the x-intercepts is plotted below
