Answer:
Step-by-step explanation:
To find the rate of change of a function, we are looking for it's slope.
We can find the slope of a line by seeing it's rise over run.
Basically - how much the line's y increases divided by how much the line's x increases.
We can see that the y drops from 1 to -1 in 1 x value. This means the change in y is , however in this case it is -2 as we are dropping.
The change in x is 1 .
This means that the slope (rate of change) is .

Answer:
D
Step-by-step explanation:
Using the addition formula for sine
sin(a + b) = sinacosb + cosasinb
and the exact values
sin( ) = cos(
) =

= +
= → D
Answer:
Step-by-step explanation:
First you have to change your fraction:
Change 7/4 into a mixed number
7/4 = 1 3/4
Then you 'guestamate' about 3/4 of the distance between 1 and 2 and mark your point. Like this:
