Question

find the range of y=-cosx+3 when x is between 0 and pi

Answer 1

Cos(0)=1
Cos(180)=1

the rest are fractions smaller than 1.

Answer 2

my bad, cos(180)=-1

Answer 3

oh okay i got it!

Answer 4

So,

\(\large\color{black}{ \bf y=-cos(0)+3 =-(1)+3=2 }\)
\(\large\color{black}{ \bf y=-cos(180)+3 =-(-1)+3=4 }\)

you won't get cosine that is \(\large\color{black}{ \bf >│1│ }\)

Answer 5

I mean any other cosine.
