Title: Precalculus assistance needed? Post by: $amanthaP24 on Oct 4, 2013 If R(x) is a rational function of the form R x = P(x)/Q(x) , then what are the restrictions on P(x) and Q(x)?
a. There are no restrictions on P(x) and Q(x) b. The only restrictions are that P(x) and Q(x) must both be polynomials c. Both P(x) and Q(x) must be non-zero polynomials d. P(x) must be a polynomial, Q(x) must be a non-zero polynomial -1^4 = a. 1 b. -2 c. -1 d. None of the above (wouldn't it be 1?) How many terms are there in the following expression: 3x^3 ? 64x^2 + 12x + (4 -2) a. 5 b. 4 c. 3 d. None Which of the following is an exponential function? a. f(x) = x^-21 b. P(x) = x^-x c. g(q) = q^-2 d. R(x)=P(x)/Q(x) If f(x) = 14^2x, then the value of the base is: a. 2 b. 2x c. 14 d. 196 cos?/tan?= a. cot? b. sin? c. csc? - sin? d. 1? sin^2 ? How many ?petals? does this function have: r = 5 sin(4?)? a. 4 b. 10 c. 8 d. 5 If v = 5i - 12j, then | v | = a. 5 b. -12 c. 7 d. 13 I^ -1 = a. 0 b. I c. 1 d. Cant find inverse Title: Precalculus assistance needed? Post by: Rika on Oct 4, 2013 the first one is d.
the second one is a. the third one is b. the second to last is c. the last one is 1/l, probably d. thats all i can help with. Title: Precalculus assistance needed? Post by: mhe34 on Oct 4, 2013 Content hidden
