Determine the equation for the quadratic function. f(x)=ax^2-6x-7 if f(2)=3

OpenStudy (oaktree):

So basically, you need the value of a where if you plug in 2 for x in the equation, you will get 3. So plug in 2 for x, set the equation equal to 3, and solve!

soo if you are saying plug in 2 for x, would it be a(3)^2-6(2)-7=3 ?
