3. which relationship represents a function?
a. {(6,-1), (4,8), (7,8), (5,6)}
b.{(–10,4), (5.0), (6,2), (7,4)}
c. {(0,0), (1,0), (5,0), (5,1)}
d.{(-2,-1), (0,0), (3,2). (4,5)}

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
