For which function would f(3) = 17
A)f(x) = 3x+6
B)f(x) = 2(x + 4)+3
C) f(x) = 5x​

B.) f(x) = 2(x + 4) +3

Step-by-step explanation:

f(x) = f(3)

2(3 + 4) +3

6 + 8 = 14

14 + 3 = 17

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
