What is the axis of symmetry for the function f(x)=7−4x+x2? edgunity

x=2

Step-by-step explanation:

f(x)=7−4x+x^2

Rewriting as

   = x^2 -4x+7

 a =1  b -4  c=7

The axis of symmetry is

h = -b/2a

  = -(-4)/ 2(1) = 4/2(1) = 4/2  =a

The axis of symmetry is x=2

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
