Answer:
y = (x-1)^2 - 2
Step-by-step explanation:
The parabola vertex point is always (h, k) in y = (x-h)^2 + k
All you have to do is look at h and k to find your vertex. Since in y = (x-1)^2 -2 has an h of -1 (Which makes it positive 1 when you plug it in) and a k of -2, that means that is your answer.
Answer:
The same way you tell if a parabola opens up or down, by the leading coefficient of the variable.
Step-by-step explanation:
Since the x-axis is positive to the right, a positive leading coefficient (3) means it opens to the right. eg. And a negative leading coefficient (-2) means it opens to the left.
Slope is y2-y1 divided by x2-x1. It doesn't matter which you put it for x2 or y2, but make sure to keep it consistent for whichever you choose to do first.
20 - 8/-18-1
12/-19
Since you can't simplify, the slope is 12/-19
A better estimate would be something that is closer to one you had before...
