Which of the statements about the graph of the function y = 2x are true? Check all of the boxes that apply. The domain is all re

al numbers x because the exponent of 2 can be any real number When the x-values increases by 1 unit, the y-value multiplies by 2. The y-intercept is (0, 1). The graph never goes below the x-axis because powers of 2 are never negative. The range is all real numbers.

Answer:

The correct options are 1, 2, 3 and 4.

Step-by-step explanation:

The given function is

f(x)=2^x

The above function is defined for all the values of x.

⇒ Therefore the domain is all real numbers x because the exponent of 2 can be any real number.

⇒ The x is exponent of 2, therefore the x-values increases by 1 unit, the y-value multiplies by 2.

Put x=0, to find the y-intercept.

f(x)=2^=1

⇒The y-intercept is (0, 1).

The value of f(x) is always greater than 0 because powers of 2 are never negative.

f(x)>0

⇒The graph never goes below the x-axis because powers of 2 are never negative.

⇒Therefore the range of the function is all positive real numbers.

Therefore the correct options are 1, 2, 3 and 4.

There are 7 people in a room. Each person shakes hands once. How many handshakes will there be?
DiKsa [7]

7 people so first one shakes hand with the remaining people. that is 6

The 2nd person also shakes hand with 6 persons but we have already counted his handshake with first person. so we have to add 6-1 = 5 shakes for 2nd person

like wise 3rd person shakes hand with the remaining 6-2 = 4 people

4th person with 6-3=3 people

5th person with 6-4= 2 persons

6th person with 6-5=1 person

and 7th one with no one because already he has shaken his hand with everyone.

since these people shake their hands with others only once we just have to add the obtained values

6+5 +4+3+2+1= 21

totally 21 handshakes will be there in that room

Sam gave jen 1/2 of his jujubes. Jen ate 1/2 of the jujubes and gave the rest to klye. Kyle kept 8 of the jujubes and gave the l
USPshnik [31]

Answer:

Jen ate 18 jujubes

Step-by-step explanation:

Start with Kim. She was given 10. There is no remainder.

Kyle kept 8 from the total he was given, so Kyle had 18.

Let the number of Jujubes given to Jen = x

(1/2) x = 18    Multiply both sides by 2

2(1/2)x = 18*2

x = 36

Jen ate 1/2 of 36 which was 18.

Though you are not asked, Sam must have begun this with 2*36 = 72 Jujubes.

Aidan bought a pizza cut into 5 slices. If he ate one slice for lunch, what percentage of the pizza remained uneaten?
Over [174]

Answer:

80%

Step-by-step explanation:

You started of with 5/5 once one slice was eat it became 4/5

you must then convert 4/5 into a percent

To convert a fraction to a percent, divide the numerator by the denominator. Then multiply the decimal by 100.

so 4 divided by 5 =0.8

0.8 x 100= 80

80%
