Which of the following functions has the solution (3, -2)?
Select all that apply.
(1) y=-2x+4
(2) f(x)=-x+2
(3) f(x)=-23x
(4) f(x)=3x−2
(5) f(x)=4x+11
(6) f(x)=6x−20
(3,−2)or x=3and y=f(x)=−2
(1)y=−2x+4|x=3y=−2×3+4y=−6+4y=−2Yes y=f(x)=−2
(2)f(x)=−x+2|x=3f(x)=−3+2f(x)=−1No f(x)=−1
(3)f(x)=−23x|x=3f(x)=−23×3f(x)=−69No f(x)=−69
(4)f(x)=3x−2|x=3f(x)=3×3−2f(x)=9−2f(x)=7No f(x)=7
(5)f(x)=4x+11|x=3f(x)=4×3+11f(x)=12+11f(x)=23No f(x)=23
(6)f(x)=6x−20|x=3f(x)=6×3−20f(x)=18−20f(x)=−2Yes y=f(x)=−2
