Which of the following is an exponential function? a) f(x)=5x-6
b) f(x)=2/x
c) f(x)=3x^3
d) f(x)=3^x

d) f(x)=3^x

Step-by-step explanation:

it is written in exponential function form

step-by-step explanation:

if x = 2 you have to find x to finish the problem

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
