Question

Can you help me with my work?

Answer 1

to find the x intercepts make f(x)=0

`f(x)=3\cdot(x+4)\cdot(x-6)`
`0=3\cdot(x+4)\cdot(x-6)`

since this is a product both of the factors involving x should be equal to 0

`\begin{gathered} x+4=0 \\ x=-4 \\ x-6=0 \\ x=6 \end{gathered}`

the x-intercepts of the function are

`(-4,0)\text{ and (6,0)}`
