Please help me if you know how to do it please

Problem 1

Answers:

A) vertical shift down 5

D) horizontal shift right 4

Explanation:

The replacement of x with x-4 means we shift the xy axis 4 units to the left, giving the illusion the curve shifts 4 units to the right. The -5 at the end effectively subtracts 5 from the y coordinate so that's why we shift 5 units down.

Problem 2

Answers:

A) Vertical stretch

C) Vertical shift up 4

Explanation:

The first 2 indicates we stretch by a factor of 2. So it is twice as tall as before. The x-3 means we shift the curve 3 units to the right. The +4 at the end means we move 4 units up.

Problem 3

Choice A) y = 3(x-4)^2 - 2

Explanation:

The 3 makes the graph 3 times taller than before. The x-4 shifts the graph 4 units to the right. The -2 at the end shifts everything 2 units down.

Problem 4

Choice B)  y = -(x+6)^2

Explanation:

The negative out front is the same as -1 out front. This reflects everything over the x axis. For instance, the point (0, 36) moves to (0,-36). The replacement of x with x+6 shifts everything 6 units to the left.

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
