The parent function of f(x)=x? is reflected across the x-axis, vertically stretched by a factor of 3, and is translated up 7 units to create g. Use the description to write the quadratic function, g, in vertex form.

Help pls I’m taking a test

what is the image?

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough

x = 1/2

step-by-step explanation:

hope this !

answer is a.

hope you get it right.
