On a coordinate grid, point p is at (5, 2) and point r is at (−3, −4). points q and s are a reflection of both points across the x-axis. what are the coordinates of q and s?

q(−5, 2), s(3, −4)
q(−5, −2), s(3, 4)
q(5, −2), s(−3, 4)
q(−5, 2), s(−3, 4)

Step-by-step explanation:

When we reflect accrox x-axis, that means we have to change y-coordinates to their opposite, from positive to negative, or from negative to positive.

So, in this case, the given points are

If we reflect these points accros x-axis, they would be

Therefore, the right answer is the third choice.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
