PLEASE HELP!! which of the following is true about the function y=3(2^x)?
a. the function decreases
b. the function has a y-intercept of (0,2)
c. if the value of x increases by 1, the value of y will double
d. the function contains the point (2,4)

Answer 1

c. do u need an explanation ?

Answer 2

a) it is exponential function so it will not decrease
b) put x=0 ,y=3 (0,3) is y intercept not (0,2)
c)=it is in the power of two so yes y value will be doubbled
d)put x=2 y=12 so (2,3 ) is incorrect
just c is correct one .
