Question

What is the transformation that occurs to the equation y = 2x if it changes to y = 2x + 5?

A. The graph moves 5 units to the left.
B. The graph moves 5 units to the right.
C. The graph moves 5 units down.
D. The graph moves 5 units up.

Answer 1

imma say D

Answer 2

It either goes up 5 or goes right 5. I've always sucked at graphs, but I know the +5 would be a positive change, so it would go up or right.
Im gonna say it'll go 5 to the right

Answer 3

yea imma gonna agree with you now that i re read the qeustion

Answer 4

B

Answer 5

Not quite....if you want to shift a graph up or down...you add or subtract a number from the whole function

f(x) = x + 5 -> graph goes up 5 units

BUT if you want to move the graph left or right..you add or subtract a number from the 'x'

f(x) = (x - 5) -> moves the graph to the right 5 units

Answer 6

ah ok so yeah it would be D

Answer 7

So here....since the number 5 is being added to the function and nor just the 'x' we havea vertical shift of 5 units UP (since it is not -5)

Answer 8

hmmm i rly dont know im confused i will re-read the qeustion again

Answer 9

WHERES MAH MEDAL AT! xD

Answer 10

The original function is

\[\large f(x) = 2x\]

here is a list of some transformations using 5 as the number

\(\large f(x) = 2x + 5\) ---> vertical shift 5 units up
\(\large f(x) = 2x - 5\) ---> vertical shift 5 units down
\(\large f(x) = 2(x - 5) \) ---> horizontal shift 5 units to the right
\(\large f(x) = 2(x + 5)\) ---> horizontal shift 5 units to the left

Answer 11

so its either A or D

Answer 12

@Ambbiiee just look at my examples of the different types of shift...you'll see which one it is :)

Answer 13

Im leaning more towards A

Answer 14

Yeah its A

Answer 15

K12 Quiz?

Answer 16

no i do ecot its another form of k12

Answer 17

oh ok
