What is the average rate of change for the function f(x)=x^2+4 for the domain of -2 to 4
Neko [114]

Answer:

  2

Step-by-step explanation:

For a quadratic function the average rate of change on an interval is the rate of change at the midpoint of the interval. The rate of change of a function is given by its derivative.

The derivative of f(x) = x^2 is f'(x) = 2x. The midpoint of the interval is (4+(-2))/2 = 1. Then the average rate of change is ...

  f'(1) = 2(1) = 2

The average rate of change of f(x) on [-2, 4] is 2.

__

<em>Alternate solution</em>

The average rate of change is the slope of the line between the end points of the interval:

  m = (y2 -y1)/(x2 -x1)

  m = (f(4) -f(-2))/(4 -(-2)) = (20 -8)/(6) = 2

The average rate of change on [-2, 4] is 2.

_____

The attached graph shows the points on the curve and a line with slope 2 between them. It also shows the various slope calculations.

Complete the proof.<br><br> Prove: △VWX ≅ △XYV<br> A) AAS <br> B) ASA <br> C) HL <br> D) SAS
soldier1979 [14.2K]

Answer:

D) SAS

Step-by-step explanation:

Given:

Segment XY = segment VW

Segment XY ║ segment VW

∠ VXY = ∠ WVX (Alternate Interior angle Theorem)

Segment VX ≅ segment VX (relative property of Congruence)

Solution:

In △VWX  and △XYV

Segment VX ≅ segment VX

∠ WVX = ∠ VXY

Segment XY = segment VW

∴ By Side Angle Side Congruence Property

△VWX ≅ △XYV by SAS
