Formula f(x)=a(x-h)^2+k (h,k) is vertex Y=a (x-3)^2+1 Plug in y intercept 10=a (0-3)2+1 10=-3^2a+1 10=9a+1 9=9a A=1 Y=(x-3)2 +1 Y=x2-6x+9+1 Y=x2-6x+10 Hope this is one of your answers
the quadratic function is : f(x) = a(x-3)²+1 find a
the coefficient of the squared expression
but ; f(0) = 10
10 = a(0-3)²+1
9a+1=10 a=1
f(x) = (x-3)²+1
