Answer:
A function does NOT have two of the same number in your Domain or your X coordinates. If you go left to right you should NOT cross your line in more then one place.
Step-by-step explanation:
Answer:
See example below.
Step-by-step explanation:
If the function has the table:
x f(x)
-3 -6
-2 -4
-1 -2
0 0
Step 1 : Looking at the table, find a pattern. This table f(x) deceases by 2 each time. This is a constant rate of change called slope.
Step 2: Recognize the pattern. Since it is decreasing by 2 each time, this is a linear function. Its equation can be written using y = mx+b.
Step 3: Use the form, y =mx + b and substitute m and b.
Step 4: The slope is m . The slope is -2. m = -2.
Step 5: Find the y-intercept. b is the y-intercept or starting point where x = 0. When x=0, the table shows y=0. So b=0.
This means the rule is y = -2x.
Answer: x = 13
Step-by-step explanation:
8x + 2 = 14x - 76
78 = 6x
x = 13
Answer:
-\frac{7}{6}
Step-by-step explanation:
We can use the slope formula for the segment that joins any two points and :
which in our case gives:
Answer:
1. 1/8 ÷ 3/4 = 1/6
2. 3/5 ÷ 3/2 = 2/5
3. 4/1 ÷ 2/3 = 6
4.9/4 ÷ 6/5 = 15/8
5.22/4 ÷ 2/5 = 261/80
