The graph of y=ax^2+bx+c is given below, where a, b, and c are integers. Find a-b+c.

Find a  - b + c .

 

Hello Guest!

 

\(f(x)=0.65\cdot (x-3)^2+1\\ f(x)=0.65\cdot (x^2-6x+9)+1=0.65x^2-3.9x+5.85+1\\ \color{blue}f(x)=0.65x^2-3.9x+6.85 \)

                   a            b            c

\(a - b + c =0.65-(-3.9)+6.85\)      

\(a - b + c =11.4\)                         

I tried the factor 0.65. Does anyone know how to calculate that?
