Create an equation. Use the graph below to create the equation of the rainbow parabola.

OpenStudy (michele_laino):

since your parabola is symmetric with respect to the y-axis, then its equation is like below: \[\Large y = a{x^2} + b\] where a, and b are two coefficients to be determined

OpenStudy (itsmichelle29):

okay

OpenStudy (itsmichelle29):

How do i solve

OpenStudy (michele_laino):

now since your parabola passes at point (6,0) I substitute into the above equation x=6 and y=0, so I get: \[0 = a{6^2} + b = 36a + b\] am I right?

OpenStudy (itsmichelle29):

IDK

OpenStudy (itsmichelle29):

=(((((

OpenStudy (itsmichelle29):

no your not i check you equation onilne

OpenStudy (michele_laino):

if I susbstitute x=6 and y=0, into my equation I get: |dw:1436731567990:dw|
