x + (x + 3) + = 75
so you will add up all of the x 's but NOT the x^2
2x + 3 + = 75
Rearrange to put the x^2 in front of 2x
+ 2x + 3 = 75
subtract the 75 from both sides
+ 2x - 72 = 0
Answer:
y = x -2
Step-by-step explanation:
The simplest function rule that will match the two given inputs and outputs is a linear function. We see that the output changes by -1-(-4) = 3 when the input changes by 1-(-2) = 3, so the slope is 3/3 = 1.
The output is 2 less than the input for both of the given table values, so we can write the rule as ...
y = x - 2
The table will look like the one attached. (Given value pairs are highlighted.)
