Question

What is the vertex of the graph of y = 5(x + 4)2 + 3?

(−4, 3)
(4, 3)
(3, 4)
(3, −4)

Answer 1

Look at the vertex formula y= a(x-h)^2+k
vertex = (h,k)
In your equation h=-4 and k=3

Answer 2

Simplify the expression then use the formula for slope: y=mx+b. B is the y-intercept and m is the slope.\[\frac{ rise }{ run}\]

Answer 3

So the first one?
