Final answer:
To find the equation of the polynomial graph with a degree of 3, zeros at x=4 and x=3, and a y-intercept at (0, -24), we can start by writing it in factored form using the zeros and then solve for the missing value of k.
Step-by-step explanation:
The given information states that the polynomial graph has a degree of 3 and zeros at x = 4 and x = 3. Additionally, it has a y-intercept at (0, -24). To find the equation of the polynomial, we can start by writing it in factored form using the zeros:
(x - 4)(x - 3)(x - k)
Next, we can use the y-intercept to find the value of k. Since the y-intercept is (0, -24), we can set x = 0 and solve for y:
-24 = (0 - 4)(0 - 3)(0 - k)
-24 = -12(0 - k)
-24 = 12k
k = -2
Therefore, the equation of the polynomial graph is:
y = (x - 4)(x - 3)(x - (-2))
Simplifying this, we get:
y = (x - 4)(x - 3)(x + 2)
