Please help me if possible.

I have three points (32; 6) (48; 14) and (64; 24)

i have to find out the equation of a quadratic function that applies to these points. (ex:y=4x^2+5.7x+83)

Please can you explain to me how its done.

i had a method of substituteing into y=ax^2+bx+c but i checked with my graphing calculator and i got it completely wrong.

Thank you so much

EDIT !!! : NEVER MIND I FOUND OUT THANKS ANYWAY
