Question

Which function represents the points included in the table?

Answer 1

F(x) can also mean y

Use data point 2 to begin with as it makes things easier because it contains a 0 x=0 y=3

A. f(x)= -3x+2

f(0)=-3(0)+2
f(0)= 0+2
y=2which doesn’t correspond with the y= 3above


B.f(x)=-2x+3
f(0)=0+3
Y=3 which does correspond with the y=3 above

C.f(x)=2x-3
f(0)=2(0)-3
y=-3 which doesn’t correspond with the y= 3above


D.f(x)=3x-2
f(0)=3(0)-2
y=-2 which doesn’t correspond with the y= 3above


So function B. f(x)=-2x+3 is the only answer
