Answer:
The axis of symmetry is at x=-2
Step-by-step explanation:
The axis of symmetry, h , is found at
h = -b/2a where a and b are the coefficients of the equation in standard form
y = ax^2 +bx +c
y = x^2 +4x+5
a =1 b=4 c=5
Then
h =- 4/2(1)
= -2
The axis of symmetry is at x=-2
Basic trig concepts you have to keep in mind:
SOH CAH TOA
Sine: Opposite of the angle over the hypotenuse
Cosine: Adjacent over hypotenuse
Tangent: Opposite over adjacent
I'll do one of the problems, you should be able to do the rest (It's good practice ;))
