[Answered] What are the zeros of the polynomial function? Select all correct zeros of each function. \begin{tabular}{l|ll} \hline Function & -3 & -2 \\ \hline$f(x)=2 x(x-3)(2-x)$ & & -1 \\ \hline$f(x)=2(x-3)^2(x+3)(x+1)$ & & 0 \\ \hline$f(x)=x^3(x+2)(x-1)$ & & \end{tabular}

[Answered] Select the correct answer. Pattie's Produce charges $[tex]$2.29$[/tex] for a package of strawberries. On average, Pattie's Produce sells 95 packages of strawberries daily. They estimate that for each 20-cent increase in the cost of a package of strawberries, 9 fewer packages will be sold each day. Let [tex]$x$[/tex] represent the number of 20-cent increases in the cost of a package of strawberries. Which inequality represents the values of [tex]$x$[/tex] that would allow Pattie's Produce to have a daily revenue of at least $[tex]$255$[/tex] from selling the packages of strawberries? A. [tex]$-1.8 x^2-21.61 x+217.55 \leq 255$[/tex] B. [tex]$-1.8 x^2+1.61 x+217.55 \leq 255$[/tex] C. [tex]$-1.8 x^2-1.61 x+217.55 \geq 255$[/tex] D. [tex]$-1.8 x^2+21.61 x+217.55 \geq 255$[/tex]

[Answered] For two functions, [tex]m(x)[/tex] and [tex]p(x)[/tex], a statement is made that [tex]m(x)=p(x)[/tex] at [tex]x=7[/tex]. What is definitely true about [tex]x=7[/tex]? A. Both [tex]m(x)[/tex] and [tex]p(x)[/tex] cross the x-axis at 7. B. Both [tex]m(x)[/tex] and [tex]p(x)[/tex] cross the [tex]y[/tex]-axis at 7. C. Both [tex]m(x)[/tex] and [tex]p(x)[/tex] have the same output value at [tex]x =7[/tex]. D. Both [tex]m(x)[/tex] and [tex]p(x)[/tex] have a maximum or minimum value at [tex]x =7[/tex].

[Answered] Determining If the Inverse Is a Function The formula [tex]F(C)=\frac{9}{5} C+32[/tex] calculates the temperature in degrees Fahrenheit, given a temperature in degrees Celsius. You can find an equation for the temperature in degrees Celsius for a given temperature in degrees Fahrenheit by finding the function's inverse. Check all that apply. A. [tex]F[/tex] is a function. B. [tex]F[/tex] is a one-to-one function. C. [tex]C[/tex] is a function. D. [tex]C[/tex] is a one-to-one function. The inverse of [tex]F(C)=\frac{9}{5} C+32[/tex] is [tex]C(F)=5 / 9 F-160 / 9[/tex]

[Answered] The town librarian bought a combination of new-release movies on DVD for $20 and classic movies on DVD for $8. Let [tex]x[/tex] represent the number of new releases, and let [tex]y[/tex] represent the number of classics. If the librarian had a budget of $500 and wanted to purchase as many DVDs as possible, which values of [tex]x[/tex] and [tex]y[/tex] could represent the number of new-release and classic movies bought? A. [tex]x=8, y=45[/tex] B. [tex]x=10, y=22[/tex] C. [tex]x=16, y=22[/tex] D. [tex]x=18, y=18[/tex]
