range is in the y-axis
so is the range 7
Use graphic calculator to solve: http://www.acalculator.com/graphing-calculator-online/
The website is kinda confusing, thanks anyway. Can anyone explain how to find the range and what it is for this equation please??
you need to graph first then find the range based off that graph which is located in the y-axis
The leading coefficient is positive so you know it looks like a smiley face. This is in vertex form with vertex \((-2,7)\). So the lowest value the function takes is \(7\).
no need to graph. That is why they gave it in vertex form. A quadratic with positive leading coefficient and vertex \((a,b)\) has range \(y\ge b\) A quadratic with negative leading coefficient and vertex \((a,b)\) has range \(y\le b\)
Oh ok so y>=7 should be my answer, right?
oh... I see. x.x if \[y \geq 7\] then we have a quadratic with a positive leading coefficient and vertex (a,b). IN this case we have a = -2 and b = 7 so (-2,7)
Yay Thank you everybody who helped
