Answer:

substitution property of equality

Step-by-step explanation:

im assuming this means that you substitute x's value of 2 into the equation y=3x2-11. i'm guessing that it's meant to be 3x2, instead of 3.2. i hope this makes sense, and i hope i answered it as you needed!

Answer: D) reflection across y = -x

Explanation:

When we reflect over y = x, we basically swap x and y. So for instance, the point (3,1) becomes (1,3).

When reflecting over y = -x, we will do the same thing but we'll make each coordinate swap in sign from positive to negative (or vice versa). The rule for reflecting over y = -x is $(x,y) \to (-y,-x)$
