Step-by-step explanation:
ratio will be
30/27
= 10/9
=10:9
Because 3/6 equals 1/2 and 2/9 equals 1/3
For this case what you should do is evaluate values of x in the function and verify that they meet the result of f (x) shown in the graph.
The answer is
f (x) = - 2lxl +1
notice that
f (1) = - 2l1l + 1 = -1
f (-1) = - 2l-1l + 1 = -1
Both comply with the value of f (x) shown in the graph
answer
f (x) = - 2lxl +1
She 56/92 6-5=1 and 567-1=566
