Answer:
the standard form is g(x)=x^2+2x-1
Step-by-step explanation:
Hello there! The vertex is where the parabola changes direction after meeting its minimum or maximum. In this case, it's where the parabola can be cut by half. As we can see, going over to the right once and going down 4 brings us to the vertex. The vertex is (1, -4).

In order for an equation to be in standard form, the equation has to be in Ax+By=c form, where A is equal to the coefficient of x and B is equal to the coefficient of y, whereas c is just the constant, or the number in the equation that isn't being multiplied to a variable. In this case, you should first distribute 2y into (x-1), and then you should perform inverse operations on terms on both sides of the equation such that one side of the equation will only have terms with x and y in them and the other side of the equation will only be a numerical value. When the equation is like this, then the equation is in standard form.
