Question

which function is best represented by this graphA) f(x) = x² - 3x + 8B) f(x) = x² - 3x - 8C) f(x) = x² + 6x + 8D) f(x) = x² + 6x - 8

Answer 1

Given the graph;

The axis of symmetry and vertex of the graph are;

`\begin{gathered} x=-3 \\ (-3,-1) \end{gathered}`

Also, the x-intercepts are;

`(-4,0),(-2,0)`

And the y-intercep is;

`(0,8)`

Thus, the function that best represents the graph is;

`f(x)=x^2+6x+8`
