What is the axis of symmetry for the function f(x)=7-4x+x??
ox = -3
ox = -2
х = 2
х= 3

F (x) = 7-4x+x^2

-b/2a

4/2•1

2

the axis of symmetry is 2

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
