Question

What transformation has changed the parent function f(x) = (.5)x to its new appearance shown in the graph below?

Answer 1

is the x supposed to be an exponent

Answer 2

Yes maams sorry :O

Answer 3

well, we plug in x = -1 to (0.5)^x then we get 2

the new function has (-1,0.5) so we have shrunk by a factor of 1/4

Answer 4

so you would multiply the whole thing by (1/4) to get your answer

Answer 5

ans should be something like (1/4)(.5)^x

Answer 6

o.o I FORGOT TO POST THE ANSWER CHOICES JFSODSDJSDO

Answer 7

f(x) − 2
f(x + 2)
f(x) + 1
−1 • f(x)

Answer 8

oh dear

Answer 9

Sorry >_<

Answer 10

well, it went from (0,1) to (-2,1) so the graph got shifted to the left 2 units

Answer 11

any idea which choice matches?

Answer 12

The first one? :O

Answer 13

not quite, that would be translating down 2 units, not left

hint: f(x+h) means a translation to the left by h units

Answer 14

Oh waittt the third one? o.o

Answer 15

we want to translate to the left by 2 units

you have the formula f(x+h) which will translate to the left by "h"' units

replace "h" with "2" to get your answer

Answer 16

I KNEW IT! THE SECOND ONE!

Answer 17

good, that's your ans

Answer 18

Yay! Thank you! :D
