Answer:
(4,-7) is the vertex
Step-by-step explanation:
The equation of the parabola is of the form
y= a(x-h)^2 +k
where (h,k) is the vertex
f(x) = -2(x – 4)^2 – 7
(4,-7) is the vertex
Answer:
y = 3x - 2
Step-by-step explanation:
<em>use y = mx + b</em>
y = -2
x = 0
m (slope) = 3
b (y-intercept) = -2, <em><u>since the point (0,-2) passes through the y a</u></em>xis.
<em>put is as slope-intercept form:</em>
y = 3x - 2

This is equal to...

We want "x" so we need to isolate it using laws of exponents...

because 
because ![x^{a/b}=\sqrt[b]{x^{a}}](https://tex.z-dn.net/?f=x%5E%7Ba%2Fb%7D%3D%5Csqrt%5Bb%5D%7Bx%5E%7Ba%7D%7D)
x = 4
answer: B
