Question

c

Answer 1

The expressions alters the x value into the y value, try plugin each x value into the expressions and compare the results with the y values. ex. try plug (first x value) into A, and see if it's not equals to the first y value, try another expression!

Answer 2

reply to your second question: first compare x and y, what is their relationship with each other? compare first x value with first y value, -2, and 4, then compare -1 and 1, 0 and 0, etc. You should find that the relationship is -2^2 = 4, -1^1= 1, 0^0 = 0, so the equation for this relationship is (x^x = y), so when x = 10 what is y? hint: plug x into the relationship equation
