Question

If anyone could help me with this it would be much appreciated and helpful to me

Answer 1

The Solution:

Given:

`g(x)=x^2+10x-7`

We are required to find the key features of the given function.

Below is the graph of the function:

Thus, the correct answers are:

`The\text{ vertex}=\text{ minimum }(-5,-32)`
`Axis\text{ of symmetry: }x=-5`
`The\text{ y-intercept}:\:\left(0,\:-7\right)`

The x-intercepts are:

`\begin{gathered} \mathrm{X\:}-i\mathrm{ntercepts}:\:\left(-5+4√(2),\:0\right),\:\left(-5-4√(2),\:0\right), \\ Or \\ X-intercepts:\text{ }(-10.657,0),\text{ }(0.657,0) \end{gathered}`
