I hope this helps you
x= -2
f (-2)= -2-7
f (-2)= -9
A_{n+1}b_{n+1} / a_{n}b_{n} =( a_{n+1} / a_{n}) * ( b_{n+1} / b_{n} ) = ( r1 ) * ( r2) =>
{a_{n}b_{n}} a geometric sequence; the common ratio is ( r1 ) * ( r2) .
Answer:
See explanation
Step-by-step explanation:
The given function is 
To create a table we choose some values of x and plug it into the function and solve for y.
When x=-1, 
When x=0 y=0+4
When x=1, y=4+1=5
When x=2, y=6
The table looks like;
x y
-1 3
0 4
1 5
2 6
Not 100% but I’m thinking 125
6 + 18 / 3 * 4
24 / 12 -Add 6 and 18, then divide 3*4
= 2
Hope this helps!
