2(9n - 6) + 52 = 2(7n + 8)
STatiana [176]

Step-by-step explanation:

2×9n=18n

2×-6=-12

52-12+18n= 38 +18n

2×7n=14n

8×2=16

14n+16

38+18n=14n+16

subtract 14n from 14n and 18n

38+4n=16

subtract 38 from 38 and 16

4n=-22

divide each side by 4

n= -5.5

For example at ;

x=-2, f(x)=0

x=-3, f(x)= 16

x= -4, f(x)= >64

This shows that as x values approach -∞, f(x) approach +∞
