Step-by-step explanation:
A function
is given.
It is required to evaluate the function at
.
To evaluate the function, substitute the indicated values in the given function to determine the output values and simplify the expression.
Step 1 of 5
The given function is
.
To evaluate the function at f(-3), substitute -3 in the given function 
Step 2 of 5
To evaluate the function at $f(2)$, substitute 2 in the given function.

Step 3 of 5
To evaluate the function at f(-a), substitute -a in the given function.

Step 4 of 5
To evaluate the function at -f(a), substitute a in the given function.

Step 5 of 5
To evaluate the function at f(a+h), substitute a+h in the given function. 

The answer is D. because the x-value is positive and the y-value is negative
So you correctly wrote that the slope is represented by
Δy/Δx. The Greek capital letter delta means "change in," so we are looking at the change in y divided by the change in x. You might also hear this called "rise over run," because change in y is the vertical change (rise) and change in x is the horizontal change (run).
Now, to find the change in y and x, we need to take two points,

and

. We can then find the slope, m, as below:

So, as we're asked to state the slope and the behavior of the graph. Generally, if you see that as x increases, y increases, then the slope is positive. If y decreases, then the slope is negative. If y stays the same (constant), then the slope is zero. If x is constant, then the slope is undefined. Unfortunately, this worksheet also asks us to calculate the slope. So the equation above comes in handy!
1) let's take x = -1, y = -5 and x = 0, y = 3. We can write

and

(we can choose either point to be

so long as we're consistent.

This is a positive (+) change.
2)

Negative (–).
3)

Positive (+).
4)

Positive (+).
5)

Negative (–).
