Answer:
C. -∞ < x < ∞
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We see that our x-values can be any number. Therefore, we have all real numbers as our domain:
(-∞, ∞) or -∞ < x < ∞
Answer:
The rate of change of function g is: 3/2
Step-by-step explanation:
Given the table of function g
x y
2 4
4 7
6 10
8 13
We know that rate of change is also termed as the slope of the function.
Thus,
let us take any two points, let say
(2, 4) and (4, 7)
Determining the slope between (2, 4) and (4, 7)
(x₁, y₁) = (2, 4)
(x₂, y₂) = (4, 7)
Using the formula
Rate of change or Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [7 - 4] / [4 - 2]
= 3 / 2
Thus, the rate of change of function g is: 3/2
3 number of days are given form different activities of sales and purchase.
Day 2:
Earnings : $16
Spendings : $7.
Day 3:
Earnings : $22
Spendings : $12.
Please note: We always add the Earnings and Subtract the Spendings.
Therefore, the expression can be used to model the situation for these 2 days as
First day earning - First day spendings + Second day earning - Second day spendings
16-7 + 22 -12.
In order to write the expression as adding the additive inverse, we need to factor out minus from second group by making expression into two groups.
We will write two positive numbers in first group and two negative numbers in second group.
(16+22) + (-7-12).
Factoring out minus sign from second group, we get
(16+22) - (7+12)
This expression in additive inverse form now.
6 tenths or 6/10
it doesn't matter how many zeros you have after the .6 it's still 6 tenths. It can have a hundred zeros it will still be just .6 = 6/10 = 6 tenths
Hope that helps you. :-)
Answer:
therefore angle Y will be equal to angle X by vertically opposite angle as by taking all the angles inside the traingle will be equal to Y so Y = X = 60°
