- Sketching the Graph of a Polynomial Function In Exercises 71-84, sketch the graph of the function by (a) applying the Leading Coefficient Test, (b) finding the real zeros of the polynomial, (c) plotting sufficient solution points, and (d) drawing a continuous curve through the points. f(x)=48x2+3x4arrow_forwardFinding a Polynomial Function In Exercises 53-62, find a polynomial function that has the given zeros. (There are many correct answers.) 2,5arrow_forwardFinding Real Zeros of a Polynomial Function In Exercises 33-48, (a) find all real zeros of the polynomial function, (b) determine whether the multiplicity of each zero is even or odd, (c) determine the maximum possible number of turning points of the graph of the function, and (d) use a graphing utility to graph the function and verify your answers. f(t)=2t42t240arrow_forward
- Fill in the blanks. The Theorem states that if fis a polynomial function such thatf(a)f(b),then, in the interval [a,b],ftakes on every value between f(a)and f(b)arrow_forwardFill in the blanks. A function is a second-degree polynomial function, and its graph is called a .arrow_forwardApproximating Zeros In Exercises 71-76, (a) use the zero or root feature of a graphing utility to approximate the zeros of the function accurate to three decimal places, (b) determine the exact value of one of the zeros, and (c) use synthetic division to verify your result from part (b), and then factor the polynomial completely. h(t)=t32t27t+2arrow_forward
- True or False? In Exercises 99-102, determine whether the statement is true or false. Justify your answer. If f is a polynomial function of x such that f(2)=6andf(6)=6, then f has at most one real zero between x=2andx=6.arrow_forwardFill in the blanks. When x=a is a zero of a polynomial function f, the three statements below are true. (a) x=ais a of the polynomial equation f(x)=0. (b) is a factor of the polynomial f(x). (c) (a,0)is an of the graph of f.arrow_forwardFill in the blanks. A polynomial function is written in form when its terms are written in descending order of exponents from left to right.arrow_forward
- Fill in the blanks. When a real zero xa of a polynomial functionfis of even multiplicity, the graph of fthe x-axisatx=a,and when it is of odd multiplicity, the graph of f the x-axisatx=a.arrow_forwardWrite a third-degree polynomial function with real coefficients and the given zeros. 5,iarrow_forwardError Analysis Describe the error in finding a polynomial function f with real coefficients that has 2,3.5, and i as zeros. A function is fx=x+2x3.5xi.arrow_forward
