What is the equation for the axis of symmetry of a parabola?

The graph of the parabola is represented by the quadratic function

y = a( x - p )2 + q which has an axis of symmetry represented by the equation of the vertical line x = p.

Step-by-step explanation:

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.
