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:
Expand the term to find the degree of the function:
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 crosses the
Notice that values of
Sketch the graph:
