Question

Help. find the vertex and maximum value of f(x)
f(x)=-2/7(x-4)^2+3

Answer 1

the general form quadratic equation is
f(x) = a(x-h)^ + k
with (h,k) as the vertex and k as the max value

Answer 2

so, from the equation we can look its answer
so,, if given f(x)=-2/7(x-4)^2+3
it means the vertex = (4,3) and the max value = 3
