Sketch the graph of a polynomial function with the following characteristics. Zeros at 1 and 3.5

Relative maximum and y-intercept at (0,4)

Relative minimum at (-1, 2.5)

Relative minimum at (2.5, -10)

Range: [-10,∞)

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.
