is the cosine curve with 5 as the amplitude and is shifted 1 units up.
(which is the function in this problem) has period 
. Period would have changed if there was any coefficient of x in the argument. But it doesn't so period is NOT 
.
, which means that if we plug in 
into x, it should give us 0. Let's check:
. It's not true.
ranges from -5 to 5. But this part is shifted 1 units up, so the max amplitude is 
and the min is 
. So we can say that the range of the function is the set of real numbers from -4 to 6. This choice is correct.
Which of the following is true for f(x) = 5cos(x) +1?
a.) the period of the function is...

Which of the following is true for f(x) = 5cos(x) +1?
a.) the period of the function is 10 pi
b.) the function has an amplitude of 2.5.
c.) a zero of the function is ( pi/2, 0 )
the range of the function is the set of real numbers -4≤ y ≤ 6
