Question

F(x)=5(1-0.75)*

*= exponent of x. i have to do a T-chart and graph.

X= 0,1,2,3,and 4
have to find y

Answer 1

well if u simplify u get F(x) = 5/(4^(x)) and when plug in the data points u get
(0,5) (1,5/4), (2, 5/16) (3, 5/64) and (4, 5/256)

Answer 2

i still dont get this

Answer 3

okay, well look at 5(1-0.75)^x
since 1 and .75 are in the parentheses u can simplify and make it 5(.25)^x
do u understand that?

Answer 4

then (.25)^x is the same thing as 1/4^(x)
then multiply this by the 5 left behind
this is how i got to F(x)= 5/4^x

Answer 5

then u just plug in 0 through 4 for x and u get your y values each time. do u need any clarification?

Answer 6

ohh ok. Thanks!! :D
