Which option correctly represents the graph of f(x) = x2 +2 and describes
whether the function is even or odd?

given,

f(x)=x^2 +2

now

f(-x)=(-x)^2 +2 = x^2 +2= f(x)

since f(-x)=f(x)

the given function is even

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
