For this case we have an equation of the form: y = A (b) ^ x Where, A: initial height b: growth rate x: time Substituting values we have: y = 6 (2) ^ x Answer: An equation that best represent how tall the sunflower will b in x weeks is: y = 6 (2) ^ x
in the linear equation the greatest power of the variables is 1 for example:2X+4 this is a linearequationasthegreatestpowerofthevariableX is 1also by drawing it in a graph you will obtain a straight line
while in the quadratic equation the greatestpoweris2for instance:X^2+4X-3 this is a QuadraticequationbecausethegreatestpowerofthevariableX is 2also by drawing it on a graph you will obtain a parabola which is a curve "an upward curve or downward curve"
