Triangle DEF is reflected over the x-axis. The vertices are: D(0, 0), E(1,3), 25 pc F(3,0). Which set of ordered pairs represents the vertices of D'E'F? *
O (0,0).(-1,3), (-3,0)
O (0,0), (1, -3), (3, 0)
O (0,0).(-1, -3), (-3,0)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

answer: c
