ANSWERS 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)
⩥ Demand p(x). Answer: p denotes price and x is the amount produced
