A. The functions have the same shape. The y-intercept of y = |x| is 0, and the y-intercept of the second function is 5.
B. The functions have the same y-intercept. The second function is steeper than y = |x|.
C. The functions have the same.
D. The functions have the same shape. The y-intercept of y = |x| is 0 and the y-intercept of the second function is -5.

Answer 1

@MellamoKatie what do you think?

Answer 2

There kinda related but not really

Answer 3

LOL the dumbest answer ever xD

Answer 4

Is it D?

Answer 5

f(x)-c = shifts the graph down by c units. also what do you realize about the shape?

Answer 6

That it goes down -5

Answer 7

yep

Answer 8

o: Really? Good

Answer 9

yeah, and also look at the shape.

Answer 10

the shape is the same but the y intercept are clearly different.

Answer 11

Yeah

Answer 12

waiitt it wouldnt be D

Answer 13

A comparison with Desmos confirms your answer

Take note how things are color coded (eg: red equation with red graph)

Answer 14

Never mind it is D

Answer 15

so is it D?

Answer 16
