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)
The x-intercepts = (-3, 0) and (4, 0)
The graph of the equation showing the x-intercepts is plotted below
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
