Which of the following relations represents a function? {(-1, 3) (-2, 3) (-1, 5) (-2, 5)} { (4, 2), (4, 3), (4, 5), (4, 7)} { (-2, 1), (0, 5), (1, -3), (-2, 0)} { (-3, 1), (1, 4), (-2, 1), (0, 3)}

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

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
