First differences are ... 0-7 = -7, -1-0 = -1, 4-(-1) = 5, 15-4 = 11, 32-15 = 17.
Second differences are -1-(-7) = 6, 5-(-1) = 6, 11-5 = 6, 17-11 = 6.
The second differences are constant at 6, so the table values would be best fit by a function that is ...
_____
The degree of the polynomial function corresponds to the level of differences that are constant (when the x-values are evenly spaced).
The quadratic function that matches these values is
... y = 3x² +2x -1
... y = (3x-1)(x+1) . . . . in factored form
I need a picture in order to help
Here is a picture of a bobcat anyway
Y= 4 (- x/3 + 1, 2x (-30))
Answer:
222 miles.
Step-by-step explanation:
<u>Lets create an equation to solve this easier.</u>
<u>Let x represent the miles driven in the truck. </u>
Our equation is 238.51=.98x+20.95
All we have to do now is solve for x.
Subtract 20.95 on both sides.
217.56=.98x
Now divide both sides by .98 to isolate the variable.
222=x
