Help me please with this work I'm trying my best to figure out how to do this so if someone can help me with the right answer please help me

Rewrite y = x2 + 2x - 1 into vertex form.
y=(x+1)2−2 Use x = - b\2a to find the vertex (h, k).

Substitute a, h, and k into y = a(x - h)2 + k:
2a(x-h)+k 2ax-2ah+k

To find the extreme values of a function f(x. y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x, y)=xy

Find the solution of each of the following.

Do, h = (7, 9) (14, 18) the scale factor is
