# Is Concave Or Domed Better?

## What is concave down?

The graph of a function f is concave down when f′ is decreasing.

That means as one looks at a concave down graph from left to right, the slopes of the tangent lines will be decreasing.

Consider Figure 3.4.

2, where a concave down graph is shown along with some tangent lines..

## What does strictly concave mean?

A function f(x) is strictly concave if its second derivative f”(x) is strictly negative for all but a finite number of values of x. Example: f(x) =-x4.

## Is a rhombus concave or convex?

A rhombus with congruent sides could have sides that all measure four inches in length. A square is a parallelogram with four congruent angles (right angles) and four congruent sides, and it has all the properties of a parallelogram, rectangle, and a rhombus. Parallelograms are convex quadrilaterals.

## Do Thumbsticks improve aim?

Here’s what I found: Do thumbstick extenders work? Yes, the extenders increase the distance your thumb has to travel to fully engage the analogue stick making them less sensitive. The thumbstick extenders give you more control which in turn gives more accuracy when aiming or turning a car in game.
