Astream begins at an elevation of 200 meters and flows a distance of 400 kilometers to the ocean? what is the average gradient?

The average gradient is

Step-by-step explanation:

We have two important data to solve this problem:

1- Stream begins at an elevation (y) of 200 m

2- Stream flows a distance of (x) 400 km.

We need to calculate the average gradient. Gradient definition is the drop in elevation of a stream divided by the distance the water travel.

So, gradient (g) will be elevation (y) divided by distance (x).

Finally, the average gradient is .

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
