Answer: 5y + 4x
Step-by-step explanation:
The x coordinate of the vertex will be the average of the two zeros, here -3 and 5, so x=(-3+5)/2 = 1, f(1)=(1+3)(1-5) = -16.
Answer: (1, -16)
Let's do it some other ways. How about completing the square to turn f in to vertex form?
f(x) = (x+3)(x-5) = x² - 2x - 15 = (x² - 2x + 1) - 1 - 15 = (x-1)² - 16
and now we can read off (1, -16) as the vertex.
The other method is the vertex is x= - b/2a = - (-2)/2(1) = 1.
Three methods, same answer. Good.

Answer:
(-7, -3)
Step-by-step explanation:
Do it in two steps:
a) First mirror point (7,3) in x-axis gives (7, -3).
Then the next step...
b) ...mirror point (7, -3) in y-axis gives (-7, -3)
Please understand that the outcome is the same, if you first mirror in y-axis and then mirror in the x-axis.
Just to demonstrate this:
a) If you irst mirror point (7,3) in y-axis gives (-7, 3).
Then the next step...
b) ...mirror point (-7, 3) in x-axis gives (-7, -3)
