Samantha buys one vase and x roses. the vase costs $15 and each rose costs $2.

what function equation represents the amount of money samantha spends?

f(x)=15x−2
f(x)=2x+15
f(x)=2x−15
f(x)=15x+2

Step-by-step explanation:

Hi there!

The answer is second one because,

x roses and each rose costs $2 so we multiply x and $2 and then we add $ 15

You can ask anything ‘bout the question if u didn’t understand.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

the answer is two. hope this !
