Three functions are given below: f(x), g(x), and h(x). Explain how to find the axis of symmetry for each function, and rank the functions based on their axis of symmetry (from smallest to largest).
f(x) = –2(x − 4)2 + 2
g(x) = 5x2 − 10x + 7

Best ResponseYou've already chosen the best response.1if we have a generic parabola: \[\Large y = a{x^2} + bx + c\] then its simmetry axis, is given by the subsequent equation: \[\Large x =  \frac{b}{{2a}}\]

Best ResponseYou've already chosen the best response.1for example, for g(x), we have the subsequent coefficients: a=5, b=10 c=7, so the equation of the symmetry axis, is: \[\Large x =  \frac{b}{{2a}} =  \frac{{  10}}{{2 \times 5}} = ...?\]
