To find: all real zeros of the function.
The real zeros of the function
Given information:
The function
Formula used:
The Rational Zero Theorem:
If
Calculation:
Consider the function
The constant term is
The leading coefficient is
Therefore, each and every rational zero is (write all combinations of factors of
factors of
Simplify all fractions:
From the graph, we see that all zeros are between
Also, from the graph, we see that
Use synthetic substitution:
So,
(Read the coefficients of the quotient from the final row.)
To find other zeros, solve the equation
The solution of the equation
Here
So, other zeros are
