PAPER 2026 QUESTIONS WITH SOLUTIONS
GRADED A+

◉ Finding Domain. Answer: Rule 2) cannot take the square root of
negative number


set what is inside radical >= 0 and solve


*make number lines*


◉ Polynomial Function. Answer: ex: f(x)= 2x^4 + 3x^2 - 10x


all powers must be *non negative whole numbers* cannot have
negative powers, square roots, or fractional powers


the *degree* of the function is the highest power (in this case 4)


◉ Rational Function. Answer: ex: f(x)= (x^3 +5x^2 -7) / x+1


It is the QUOTIENT of 2 polynomials
This means NO negative powers, square roots or fractional powers

, *does NOT have a degree*


◉ Power Function. Answer: ex: f(x)= 2x^5, 3x^-2, square roots, etc


Powers can be any real number (including negatives and fractions)


*does NOT have a degree*


◉ All polynomial functions are power functions.... Answer: but the
reverse is not true! Not all power functions are polynomial functions


◉ Equilibrium Point. Answer: occurs where the supply function
equals the demand function


s(x) = d(x)


◉ To find equilibrium *quantity*. Answer: set s(x)=d(x) and solve
for x


◉ To find equilibrium *price*, p. Answer: set s(x)=d(x) and solve for
x and plug it back into either s(x) or d(x)
