Determine the inverse for the function: P (x) = 2x 2 + 1

P -1 (x) = $$\sqrt[]{\frac{x-1}{2}}$$

P -1 (x) = $$\sqrt[]{\frac{x+1}{2}}$$

Determine the inverse for the function: Q(x) = $$\frac{2x\ -7}{4}$$

Q -1 (x) = $$\frac{7x\ -2}{4}$$

Q -1 (x) = $$\frac{2x\ +4}{7}$$

Determine the inverse for the function: S (x) = $$\frac{2x^2\ -7}{4}$$

S -1 (x) = $$\sqrt[]{\frac{4x+7}{2}}$$

S -1 (x) = $$\sqrt[]{\frac{2x+7}{4}}$$
