OpenStudy (sohailiftikhar):

exponential you said huh ?

OpenStudy (sohailiftikhar):

where are exponential function huh ?

OpenStudy (sohailiftikhar):

btw it's A

OpenStudy (sohailiftikhar):

are you there ?

OpenStudy (sohailiftikhar):

just put the value of x coordinate from given equation in all option check which function will give the right value of y coordinate ...right answer is A you can check

OpenStudy (anonymous):

@sohailiftikhar Yeah sorry and thanks, I dont need a explaination I just needed the answear. you mind helping me with some more?

OpenStudy (sohailiftikhar):

Two separate bacteria populations grow each month and are represented by the functions f(x) = 3x and g(x) = 7x + 6. In what month is the f(x) population greater than the g(x) population? A. Month 1 B. Month 2 C. Month 3 B. Month 4

@sohailiftikhar

OpenStudy (sohailiftikhar):

you sure about + sign b/w 7 and 6?

OpenStudy (anonymous):

@sohailiftikhar what?

OpenStudy (sohailiftikhar):

is this Question correct you sure ?

OpenStudy (sohailiftikhar):

i think sign between 7x and 6 is negative

OpenStudy (sohailiftikhar):

because in this way f(x) can't be greater at any positive value than g(x)

OpenStudy (sohailiftikhar):

dude ?

OpenStudy (sohailiftikhar):

right equation is \[f(x)=7x-6 \] and so the answer is 1month

OpenStudy (sohailiftikhar):

i'm going now
