Question

The graphs of four exponential functions are shown below:

graph of 4 exponential curves. Curve A joins the ordered pairs negative 2.2, 22 and 0, 4 and 6, 0. Curve B joins ordered pairs negative6, 0 and 4, 0 and 2.1, 22. Curve C joins the ordered pairs negative6, 0 and 0, 1 and 2, 16. Curve D joins the ordered pairs negative4, 0 and 0, 1 and 4.2, 22

Which pair of graphs should be plotted to show the solution to 4x = 2x?

Graphs A and B
Graphs B and C
Graphs C and D
Graphs A and D

Answer 1

Answer 2

check your info, your missing something i think at the end

Answer 3

also give me your thoughs

Answer 4

the 4x and 2x are exponents

Answer 5

4^x and 2^x ?

Answer 6

yes

Answer 7

now tell me your thoughts ... which one would you choose?

Answer 8

a

Answer 9

hmm, what is 4^0 and 2^0?

Answer 10

4 and 2

Answer 11

.... nope

Answer 12

try again?

Answer 13

0 and 0

Answer 14

@amistre64

Answer 15

no, b^0 = 1 for all b other than b=0

Answer 16

4^0 = 1
2^0 = 1

therefore, when x=0, we have 2 curves that cross at y=1

Answer 17

c and d? @amistre64
