Step-by-step explanation:
can be broken down into three fractions, coefficients, powers of p, powers of q.
Simplify the first fraction, then simplify the others by subtracting numerator exponents minus denominator exponents.

To find f(5) ⇒ substitute with x = 5 in the function → x²
∴ f(5) = 5² = 25
To find f(2) ⇒ substitute with x = 5 in the function → x²
∴ f(2) = 2² = 4
To find f(-2) ⇒ substitute with x = 5 in the function → 2x
∴ f(-2) = 2 * (-2) = -4
To find f(1) ⇒ substitute with x = 1 in the function → 5
∴ f(1) = 5
