Question

If the equation y=2^x is graphed, which of the following values of x would produce a point closest to the x-axis?
A) 1/4
B) 3/4
C) 5/3
D)8/3

Answer 1

do you know how the graph of y=2^x looks like?

Answer 2

no

Answer 3

how about answering this... if a point was very close to the x-axis, what would you be able to tell me about the y-coordinate of that point?

Answer 4

y=0 ?

Answer 5

well, yes... the point's y-coordinate would be very close to 0.

so which of those choices will give you the smallest y-value?

Answer 6

1/4?

Answer 7

idk

Answer 8

in other words, which is the smallest value?
\(\large 2^{\frac{1}{4}} \) OR
\(\large 2^{\frac{3}{4}} \) OR
\(\large 2^{\frac{5}{3}} \) OR
\(\large 2^{\frac{8}{3}} \) ????

Answer 9

2 and 1/4

Answer 10

????

Answer 11

@dpaInc ..?

Answer 12

is it to the power of?
y=2^x
so would it be 2^1/4

Answer 13

those aren't fractions... \(\large 2^{\frac{1}{4}} \)= "two raised to the 1/4 power"

Answer 14

oh i see... so

Answer 15

so is it A because it is the smallest value, getting the closest to the x-axis?

Answer 16

@dpaInc

Answer 17

??

Answer 18

anyone?

Answer 19

yes... :)

Answer 20

a is correct?
