Question

PLEASE HELP - CHECK MY ANSWER: A.
When the function f(x) = 4(2)x is changed to f(x) = 4(2)x − 13, what is the effect?

A. There is no change to the graph because the exponential portion of the function remains the same.
B. The x-intercept is 13 spaces higher.
C. The y-intercept is 13 spaces lower.
D. All input values are moved 13 spaces to the left.

Answer 1

I find myself wondering whether you and I worked on this problem earlier today.

Please use proper math notation for showing exponentiation:

\[2^x\]

Answer 2

or

Answer 3

If I give you function f(x) and ask you to write function g(x)=f(x)+2, the graphs will be different. How and why?

Answer 4

@mathmale yes i think so but but it wouldn't let me return to the question after i posted a comment.. so. Is it not A?

Answer 5

No, it's not A.
Sorry.
I'd suggest we work thru this question again so that you'll know next time how to answer similar questions.

Answer 6

Just so that you know: The topic of this problem is "horizontal and vertical translations of graphs."

Answer 7

@mathmale sorry ha ive been working on this assignment all day and im a little tired. I meant C... to many math problems in my head

Answer 8

im pretty sure thats the answer

Answer 9

I'm sympathetic, but "pretty sure that's the answer" doesn't cut it in math.

Given f(x), which has a graph, writing f(x)+2 will move the whole graph of f(x) upward by 2 units.

Try again. Explain your answer choice.

Answer 10

@mathmale em well considering that I wont be using this in life that is the best I got. Im going to go with C because I have had a long day. Thank you

Answer 11

OK. C is correct, by the way.

Answer 12

yes I know.. (: I already submitted the assignment. Thank you anyways.. sorry for being such a jerk been a long week

Answer 13
