Whats the zeros and the vertex !

The vertex is (0,3), and the zeroes are at -1 and -7

Step-by-step explanation:

Since the function is going upward, the vertex is the minimum value

So the vertex is (0,3)

The zeros of a function are where the function touches the x-axis, or when y is 0.

We can find the zeros by making y (or f(x)) 0.

(x+4)^2-9=0

x^2+8x+16-9=0

x^2+8x+7=0

Factoring

(x+1)(x+7)=0

The zeroes are at -1 and -7.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
