Suppose a parabola has vertex (-4,7) and also passes through the point (-3.8). What is the equation of the parabola in vertex form? y=(x+4)²+7
y=2(x+4)² +7
y = 2(x+3)²+8
y=(x-4)²+7

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

translate k to n and reflect across the line containing jk.

no he doesnt because "-16' is negatiive
