Answer:
Quadratic
Step-by-step explanation:
Linear equations are straight lines while quadratics are curved in a "u" shape. These points have a vertex and go up on both sides, a quadratic would be able to better fit this since their y values repeat, unlike linear models.
For this case we have the following multiplication:

We can rewrite this operation to facilitate the calculation.
We have then:

From here, we apply the distributive property.
We have then:

Rewriting we have:

Finally adding all the numbers we have:

Answer:
The value of 6 * 298 is 1788 and the calculations can be provided as follows:

Answer:
16.5 square units
Step-by-step explanation:
You are expected to integrate the function between x=1 and x=4:

<em>Additional comment</em>
If you're aware that the area inside a (symmetrical) parabola is 2/3 of the area of the enclosing rectangle, you can compute the desired area as follows.
The parabolic curve is 4-1 = 3 units wide between x=1 and x=4. It extends upward 2.25 units from y=4 to y=6.25, so the enclosing rectangle is 3×2.25 = 6.75 square units. 2/3 of that area is (2/3)(6.75) = 4.5 square units.
This region sits on top of a rectangle 3 units wide and 4 units high, so the total area under the parabolic curve is ...
area = 4.5 +3×4 = 16.5 . . . square units
