Use the vertex and intercepts to sketch the graph of the quadratic function. Give the equation of the parabola's axis of symmetry. Use the graph to determine the domain and range of the function. f(x) =(x 3)2 4 I' ..... 1 Use the graphing tool to graph the function. Use the vertex and one of the intercepts when drawing the graph. The axis of symmetry is . ("ype an equation. Simplify your answer.) The domain of the function is . ("ype your answer in interval notation.) T (_ he range of the function is . 'ype your answer in interval notation.) Determine if the following function is a polynomial function. If it is, identify the degree. fixizxe'\" 8x+6 ' IIIII " Select the correct choice below and, if necessary, ll in the answer box to complete your choice. 0 It is a polynomial. The degree of the polynomial is Q It is not a polynomial. \fDetermine whether the function is a polynomial function. If it is. identify the degree. f(x) = 5x5 + 7x? / ..... \\ Choose the correct choice below and, if necessary, ll in the answer box to complete your choice. O A- It is a polynomial. The degree of the polynomial is O B. It is not a polynomial. Fill in the blank so that the resulting statement is true. The Factor Theorem states that if f is a polynomial function and f(c}= 0, then El is a factor of x}
