Answer:
f(-3) = 1
Step-by-step explanation:
The only point with an x-coordinate of -3 has a y-coordinate of 1. That is the value of the function f(x) for x=-3.
12.8, 11.6, 10.4, 9.2, 8.0, 6.8, 5.6
3, 1.5, 0.75, 0.375, 0.1875, 0.09375, 0.046875
The first one is arithmetic as the pattern is deducting 1.2, second one is geometric as it is dividing 2.
the answer is x=-1
