What is the maximum number of turns in the graph of this function? f(x)=x^4-x^3 3x 1

Maximum number of turns: 3

Step-by-step explanation:

1. By definition, a polynomial of degree, has a maximum turning points of:

 .

2. Therefore, if you have the polynomial given in the problem, which is a polynomial of degree 4 (), the maximum number of turns can be obtained as following:

3. Therefore, you can conclude that the maximum number of turns are 3.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
