Use the Intermediate Value Theorem and the table feature of a graphing utility to find intervals one unit in length in which the polynomial function is guaranteed to have a zero. Adjust the table to approximate the zeros of the function. Use the zero or root feature of the graphing utility to verify your results. \(h(x)=x^{4}-10 x^{2}+3\)
Determine whether each value of \(x\) is a solution of the inequality. Inequality. \(\begin{array}{lll}\frac{x+2}{x-4} \geq 3 & \text { (a) } x=5 & \text { (b) } x=4 \\ & \text { (c) } x=-\frac{9}{2} & \text { (d) } x=\frac{9}{2}\end{array}\)
A company that manufactures bicycles estimates that the profit \(P\) (in dollars) for selling a particular model is given by \(P=-45 x^{3}+2500 x^{2}-275,000, \quad 0 \leq x \leq 50\) where \(x\) is the advertising expense (in tens of thousands of dollars). Using this model, find the smaller of two advertising amounts that will yield a profit of $$\$ 800,000\(.\)
