f(x) = (3)^x - 2

The function f(x) is shifted to the left by 13 units. Which of the following best represents the new function?

ANSWER CHOICES
f(x) = (3)x + 11

f(x) = (3)x + 13

f(x) = (3)x -15

f(x) = (3)x - 13

Answer 1

ANSWER CHOICES

Answer 4

I'd say C but I'm not sure.

Answer 5

@suckerofmath oh i forgot, anything after the parenthesis is exponent, so for C it would be f(x) = (3) to the power of x-5

Answer 6

well you'll need to look at the indexes

what value of x makes

x - 2 = 0 Solution

and to move it 13 to the left...

its 13 - solution = answer

then it will be

3^{x + answer}

hope it makes sense

Answer 7

@campbell_st so... C ?

Answer 8

nope... the solution to

x -2 = 0

is

x = 2

now what is 13 - 2 = Answer

and the solution is

3^(x + answer)

Answer 9

3^(x+11) ??

Answer 10

thats what my answer would be

Answer 11

@campbell_st alright, ill choose A then wish me luck, can you help me with another one ?

Answer 12

sorry... I have to go and walk the dogs...
