You cannot answer this question with the information supplied.
The x intercepts are the roots of the polynomial f(x) = 0.
The fundamental theorem of algebra says that the number of roots of this equation is 9, but not necessarily all of them are real; therefore the MAXIMUM number of x intercepts is 9.
However, since f(x) is of odd degree it must have at least one real root; therefore, the MINIMUM number of x intercepts is 1.

Need help solving this limit problem.
evablogger [386]

Answer:

c= -1.8

Step-by-step explanation:

A function is continuous at a point x if the limits at x from above and below coincide (are equal). Hence,

Limit from above: \lim_{x\rightarrow\-1^+}f(x)=4c(-1)=6 = -4c-6

Limit from below: \lim_{x\rightarrow\-1^-}f(x)=c(-1)^2+3=c+3

And so when these limits are equal we obtain

c+3=-4c-6\\5c=-9\\c=-1.8

Calculate the length of a triangle if another length is 15 feet and the hypotenuse is 39 feet.
Y_Kistochka [10]
We have to use Pythagorean theorem that says : 

a^2+b^2=c^2\\\Rightarrow a^2+15^2=39^2\\a^2=39^2-15^2\\a=\sqrt{1296}\\a=36

The missing length of the triangle is : 36 feet
