Answer to Problem 3E
The statement “the function graphed at the right has two zeros ,-2 and -1.” is false.
Explanation of Solution
Given information:
The statement “the function graphed at the right has two zeros, -2 and -1.”
Consider the provided statement “the function graphed at the right has two zeros, -2 and -1.”
Recall the definition of root of the function − the solution of an equation is called the root of the equation.
The equation is
Re-writing the equation we get,
Now,
Therefore, the root of the equation is
Thus, the statement “the function graphed at the right has two zeros , -2 and -1 .” is false.
