Concept explainers
Find the degree and zeros of the given function.
Explain the multiplicity of zeros and show whether the graph pass through the
Sketch the graph.
The degree of the function is
The zeros of the function
Given:
Find the degree of the function:
Rewrite
Expand
Simplify and combine like terms:
Apply the distributive property:
Simplify the term:
Use the Binomial Theorem:
Expand the term by multiplying each term in the first expression by each term in the second expression:
Simplify terms.
The largest exponent is the degree of the polynomial, so the degree is
Find the zeros:
To find the zeros, solve the related equation
Apply the zero-factor property:
Hence, the zeros of function
Explain the multiplicity of zeros and show whether the graph pass through the
The graph does not cross the
Notice that values of
Sketch the graph:
The graph of the function
