The vertex of this parabola is at (-4, -1). when the y-value is 0, the x-value is 2. what is the coefficient of the squared term in the parabola's equation?

Can someone plz me understand how to do these. plz, show work.in exercises 1-4, rewrite the expression in rational exponent form.[tex]\sqrt[4]{625} \sqrt[3]{512} (\sqrt[5]{4} )³ (\sqrt[4]{15} )^{7}\\ (\sqrt[3]{27} )^{2}[/tex]

Find the value of x. also give me an explanation so i can complete it to other questions as well, : )
