Question

Can anyone help me!?!?!?!?! Here is my question:

Compare the functions shown below:
f(x) = 4 sin (2x − π) - 1
g(x)

x y
-1 6
0 1
1 -2
2 -3
3 -2
4 1
5 6
h(x) = (x − 2)2 + 4

Which function has the smallest minimum y-value?,

Answer 1

The sine function has a minimum value of -1, so f(x) = 4sin( ) -1 will have a minimum value of -5.

g(x) obviously has a minimum value of -3.

h(x) has a squared term that cannot be negative, so its minimum value is +4.


f(x) has the smallest minimum value.
