The equation of a parabola in the xy-plane is given as y= n(x + 5)(x - 3) where n is a non-zero constant. What
is the y-coordinate of the vertex of this parabola in
terms of n?
A. -18n
B. -16n
C. -15n
D. -12n

B

Step-by-step explanation:

y=n(x+5)(x-3)

or y=n(x²-3x+5x-15)

or y=n(x²+2x-15)

=n(x²+2x+1-1-15)

=n(x+1)²-16n

y -coordinate of vertex=-16n

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
