Answer:

B. I, II, and III

Step-by-step explanation:

A function is continuous if it is defined everywhere and its graph can be drawn without lifting the pencil. That is, at every point, the limit from the left and the limit from the right must equal each other and the function definition at the point.

<h3>Looking at choices</h3>

All polynomial functions with real coefficients are continuous everywhere. (Choices I and II.) They have no discontinuities.

Rational functions will have a discontinuity wherever the denominator is zero. Here, the one rational function has a denominator of x^2+1, which is always positive (never zero). The given rational function is continuous everywhere (Choice III.)

All of the functions in the problem statement are continuous: I, II, and III.

What are the coordinates of the vertex for f(x) = 2x2 + 4x + 9?

Vlada [557]

Your equation $f(x)=2x^2+4x+9$ is in the form $y=ax^2+bx+c$
The vertex only relies on "a" and "b" though, so that +9 doesn't really matter in this case. The vertex of a parabola is located where
$x=\frac{-b}{2a}=\frac{-4}{2(2)}=-1$
So your x-coordinate is -1. You need to find f(-1) to find your y-coordinate, and then you list it in the form (-1, y).

What is the value of x? Please answer details are below

nydimaria [60]

Answer:

Step-by-step explanation:

Angles in a triangle add to 180° and we can see a right angle so

x = 180 - ( 90 + 36 )

x = 180 - 126

x = 54

What is the equation in slope-intercept form

Answer:

Step-by-step explanation:

Slope is rise/run, so the fraction would be more likely to be the correct answer.

Write the equation of the line, in slope-intercept form, that contains the points (-1,-2) and (1,2)

Bad White [126]

Slope intercept is y=mx+b
m=slope
slope if found by
m=(y1-y2)/(x1-x2)
(x,y)
(-1,-2) and
(1,2)
x1=-1
y1=-2
x2=1
y2=2

m=(-1-1)/(-2-2)
m=-2/-4
m=1/2

y=1/2x+b
solve fo by subsituting one x value
(1,2)
x=1
y=2
2=1/2(1)+b
2=1/2+b
subtract 1/2
3/2=b

equation is
y=1/2x+3/2

L has $200. Ty has 30% more than Lu and twice as much as Ali. How much money do they have altogether? (PLEASE SHOW STEPS!)

saul85 [17]

30% of 200=60 200+60= 260
Ty has £260
£260 x 2= £520

200+260+520= £980

Answer £980

I hope this is right :D
