Find the x-intercepts of the parabola with vertex (1,20) and y-intercept (o,16). write your answer in this form: (x1,,y2). if necessary, round to the nearest hundredth.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.

444(2)4-2(7)2+40=? 8(4)-14(2)+40=? 32-28+40=? 4+40=? 44

Finish the question.
