Answer: No this is not a linear function as the y values have different first differences.
Step-by-step explanation:
First we look at the x values. We start off and look at the second x value and subtract the first x value from it (That would be 1-0) and that equals to 1. Then we look at the third x value and subtract the second x value from it (2-1) and that equals to 1. Then we look at the fourth x value and subtract the third x value from it (That would be 3-2) and that is 1. Next we look at the fifth x value and subtract the fourth x value from it (That would be 4-3) and that is 1.
Now we look at the y values and do the same thing as with the x values. We start off and look at the second y value and subtract the first y value from it (That would be 1-0) and that equals to 1. Then we look at the third y value and subtract the second y value from it (4-1) and that equals to 3. Then we look at the fourth y value and subtract the third y value from it (That would be 9-4) and that is 5. Next we look at the fifth y value and subtract the fourth y value from it (That would be 16-9) and that is 7.
Even though the x values all have the same first differences, the y values do not and so this cannot be a linear function.
I hope this helps. Tell me if something doesn't make sense.
Working out the different pay rates earned by Ike Phillips :
- Time and half pay rate = $17.055
- Double pay rate = $22.74
- Time and half earning = $114.2685
- Double rate earning = $77.316
- Gross earning = $646.3845
Let :
Regular rate = $11.37
Total earning for the week = $454.80
Double pay hours = 3.4
Time and half pay hours = 6.7
- Time and half pay rate = 1.5 × regular pay rate = 1.5 × 11.37 = $17.055
- Double pay rate = 2 × regular pay rate = 2 × 11.37 = $22.74
- Time and half earning = rate × time = $17.055 × 6.7 = $114.2685
- Double rate earning = rate × time = $22.74 × 3.4 = $77.316
- Gross earning = (regular + time and half + double earning) = $(454.80+114.2685+77.316) = $646.3845
Therefore, Ike's gross earning for the week is $646.3845

Draw a diagram to illustrate problem as shown below.
Let h = the height of the tree.
Because ΔABC ~ ΔADE, therefore
DE/BC = AD/AB
That is,
h/1.94 = (5.1 + 10.2)/5.1 = 3
h = 1.94*3 = 5.82 m
Answer: 5.82 m
Answer: -3x^2-3x+9
Step-by-step explanation:
-3(x^2+x-1)+12 = -3x^2-3x-3+12 = -3x^2-3x+9
