which function will have the greatest value at x =16

Answer:
[tex]y=x^2-23x\text{ +196}[/tex]Explanation:
To find the greatest value, we plug in the value x =16 into the given functions.
For y=5x
[tex]\begin{gathered} y\text{ = 5(16)} \\ \text{Calculate} \\ y=\text{ 80} \end{gathered}[/tex]For
[tex]\begin{gathered} y=x^2-23x\text{ +196} \\ =(16)^2\text{ - 23(16)+196} \\ \text{Calculate} \\ =84 \end{gathered}[/tex]For
[tex]\begin{gathered} y=1.15^x \\ y=1.15^{16} \\ Calculate \\ y=9.36 \end{gathered}[/tex]Therefore, the function that has the greatest value is
[tex]y=x^2-23x\text{ +196}[/tex]
