3b-14/3b = 5b+2/3b <br> b= ?

WINSTONCH [101]

First of all, observe that all fractions exist as long as b is not zero.

Multiply both numerator and denominator of the first fraction by 3:

$\dfrac{3b-15}{3b}+\dfrac{1}{3b}=\dfrac{5b+2}{3b}$

Now all fractions have the same denominator. Under the assumption that b is not zero, multiply both sides by 3b:

$3b-15+1=5b+2 \iff 3b-14=5b+2$

Subtract 3b from both sides:

$-14=2b+2$

Subtract 2 from both sides:

$-16=2b$

Divide both sides by 2:

$b=-8$

Which statement describes the function below f(x)=2x^3-3x+1

Ilia_Sergeevich [38]

The given function is f(x)=2x^3+2x^2-x. In this case, the highest degree among the terms is 3. According to the Fundamental Theorem of Algebra, the number of zeros or roots of the equation is equal to the highest degree among the terms. Hence for every value of y, there are 3 equivalent x's. The answer thus is B. It is a many-to-one function.
