Question

Tip/suggestion about equation​

Answer 1

Answer:

y=5x^3-2x+1

8/x-8 = x/2x-1

√x-2=4

x-1/x+1=x^2

P(7x3−4√x+1)/Q(x2+3)P(7x3−4√x+1)/Q(x2+3)

6x-5/x+3≥0

My answers: 1. Rational equation 2. Rational equation 3. None of these 4. Rational equation 5. Rational function 6. Rational inequality

Please correct me if I have any mistake. I also wonder how f(x)=6 -x+3/x^2-5 is considered a rational function, given that the denominator and numerator are not polynomials.

Answer 2
