I'm pretty sure its 2 because doesn't it say that the total is 10

Hello!</h2>
The answer is:

<h2>Why?</h2>
Evaluating a function means replacing the variable with the given value (3 for this case).
To evaluate the function, we need to remember that the absolute value guarantees a possitive value, for example:

So, we are given the function:

Then, evaluating we have:

Hence, the answer is:

Have a nice day!
Answer: Concave down
Explanation:
An example is shown below. We have the concave down parabola
marked in red. The trapezoidal sum is in blue. The three trapezoids combine to something just a bit smaller than the true area under the curve from x = -2 to x = 1. Therefore, this trapezoidal sum is an underestimate of the true area under the curve.
Every part of each trapezoid is completely below the red curve. In other words, no part of the blue pieces spill above the parabola.
Step-by-step explanation:
-3/10+ -1/5
find the common denominator. on that case its 10
10 into 10 that's 1 so 3 remain 3 . then 5 into 10 its 2 so 1×2=2
-3/10 + -2/10
-3+-2
-3-2= -5
-5/10= -1/2
Ans is -1/2
-18/15 ×5/-4
you cross multiply. 5into 15 to get a denominator 3 then -4/2=-2 denominator. -18/2=-9. you multiply 3×-2=-6 then we are left with
-9/-6= -3/-2=1 and half
Ans is 1 1/2 (one and 1 half ).
3/8÷ -1/4
you spin -1/4 to -4/1 inorder to change the sign to a multiplication sign.
3/8 × -4/1 1
cross multiply to get -3/2
-3/2 = - 1 1/2
Ans : 1 1/2 ( one and one half )
