Question

When the function f(x) = 6(9)x is changed to f(x) = 6(9)x + 1, what is the effect?

There is no change to the graph because the exponential portion of the function remains the same.
All input values are moved 1 space to the right.
The x-intercept is 1 space higher.
The y-intercept is 1 space higher.

Answer 2

I think c

Answer 3

1) Don't post problems with no work shown.
2) 6(9)x means 6*9*x. Did you mean 6*9^x = \(6\cdot 9^{x}\)?
3) Where does the "+1" go? \(6\cdot 9^{x+1}\;or\;6\cdot 9^{x}+1\)

Answer 5

graph
y = A*B^(x - C) + D

https://www.desmos.com/calculator

hit add slider button for all, play with each one A B C D , see how it changes the graph

Answer 6

where is the add slider button

Answer 7

make B a little larger than 1

Answer 8

after you type in the equation it will show the buttons below it

Answer 9

so it is C

Answer 10

or no D

Answer 11

D right

Answer 12

yeah the whole graph shifts in ydirection

y = A*B^(x - C) + D

D has no part of what the x term does , it is just an added on constant , every Y value will be changed by D

Answer 13

So D

Answer 14

yes.

Answer 15

Thank you so much!! you are so helpful, can you help me with another

Answer 16

C - xdirection shifts, any x you had is now C different

A - scales the exponent, justmultiplies the value by an amount , you can see the effects on the graph, stretched upwards

Answer 17

sure, one more
