To get the average rate of change (ARC) of f(x) over [x1, x2], we use the formula:
ARC = ( f(x2) - f(x2) ) / (x2 - x1)
From the graph
f(2) = 4
f(-2) = 4
Plugging in the values into the formula:
ARC = (4 - 4) / (2 - (-2) )
ARC = 0
The points connecting (-2,4) amd (2,4) is a horizontal line that is the rate of change is 0.
Answer:
Step-by-step explanation:
The slope of the line is -5, and the y-intercept is 250
Answer:
6.14
Step-by-step explanation:
Find area of shaded region:
regtangle area - circle area = shaded area
Regtangle area:
3x3=9
Circle area:
Pi (3.14) x radius x radius= 3.14
area all together if shaded region
9-3.14=6.14
For this case we have the following transformation rule:
(x, y) --------> (x, - y - 2) ----------> (x ', y')
We are going to apply the following transformation rule for vertex D, for example.
We have then:
(4, 1) --------> (4, - 1 - 2) ----------> (4, -3)
Therefore, the transformation is:
Reflection on the x axis and vertical displacement 2 units down.
Answer:
a reflection across x-axis, and then a translation 2 units down
Answer:
b=(13/4, -27/4, -4)
Step-by-step explanation:
A.x=b
x=(a, b, c)
a - b + 2c = 2
3a + b + 0 = 3
0 + 0 + c = -4
solving this system
c=-4
a-b=10, 3a+b=3
a=10+b, 3(10+b)+b=3
b=-27/4
a=10-27/4
a=13/4
