I need help ASAP please!

i believe the answer your looking for would be A) (-infinity, 4)

A) (-inf,4]

Step-by-step explanation:

The range of a function is all of the y-values that are appropriate for the function.

The range has a global maximum of 4, so this is the endpoint of the range.

Notice how the range continues down to negative infinity, so this is the start of our range, and we always mark infinity in parentheses because infinity is not a number.

So the correct interval notation would be (-inf,4] where the bracket means 4 is included but -inf is not since we mentioned earlier it isn't a number.

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.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
