Question

Please help!
What are the upper and lower bounds for the function:
f(x) = sin x+ 2?

Are they asking for the local max and local min?

Answer 1

Remember that sin() has an upper value of 1 and a lower value of -1.

Answer 2

The answers can't be 3 (upper value) and 1 (lower value)... can they? That seems way too easy.

Answer 3

@pathosdebater Correct. It's that easy.

Answer 4

But when I type the equation into a graphing calc, I get the local min = -1 and the local max = 1

Answer 5

Should the equation in the calculator be y = sin(x+2) or y = sin(x) + 2?

Answer 6

I got 3 as the local max and 1 as the local min when I put y = sin(x) + 2

Answer 7

It sounds like the graphic calculator is lying.

Answer 8

About which one?
