Answer:
b. – 0.4(x + 1.6) = 1.6
Step-by-step explanation:
I believe this is how you do it
The sine function is increasing in the first quadrant.
sin(0) = 0
sin(90) = 1
This means the larger angle will give a larger sine value.
sin(w) > sin(t) -----> w > t
<u>ANSWER</u>

<u>EXPLANATION</u>
When a quadratic equation is in the vertex form,

the equation of axis of symmetry is simply

The given quadratic equation is

We can rewrite this as

We now compare to

We have

Therefore equation of axis of symmetry is:
