Question 184373: what is the wingspan of a bird weight 1.30 pound, if I use the rational exponent euation L= 2.43* W^0.3326 to estimate the wingspan L in feet of the bird"s weight.
I start of like this
L = 2.43* w^0.3326
L = 2.43* 1.30^0.3326
L =

Question 184528: I'm can't figure out how to create a quadratic equation out of the vertex and a point that it must pass through. All i've managed so far is some trial and error and come up with this.
y=2(x+2)²+4
From the vertex of (-2,4) and passing through (-1,8).
I have been fiddling around with it and have two ideas how to proceed.
I could change (x+2) to something else to move it along the x axis or change the first part of it to change the fatness or whichever you want to call it of the parabola. Regardless i figure there is a better way to do it other then trial and error, if it has been answered before i'm sorry I didn't see it. I'm self taught and this is the first time I really have had any problem.
