This is the input/output table for a linear function. Linear functions increase or decrease by a constant value (the slope).
(38 - 19) / (2 -1) = 19
See how every output is +19 the one before it?
then the output following 57 is 57+19 = 76
1 is one 19
2 is two 19's
3 is three 19's
n is 19n
It is important to Remember the negative exponent law.
X^-m = 1/X^m
1/10^2 = 10^-2.
ANSWER
Eva is correct because 13/2 + 3/2 = 8
There is no mistake. Dakota may have thought that there was a mistake because Eva simplified when she got the answer for 4x which is correct but Dakota may have thought that it was incorrect.
