Answer:
a) -4
b) 2
Step-by-step explanation:
a) f(-2) = 3*-2 + 2 = -4
b) f(x) = 8
3x + 2 = 8
3x = 8 -2
3x = 6
x = 6/3
x = 2
Answer:
Exponential
374.4
Step-by-step explanation:
This function is not linear. You can tell because the f(x) values do not increase by adding the same number each time.
163.84 + 81.83 = 245.67
245.67 + 122.88 = 368.64
The rate of change is different each time.
The average rate of change from x = 2 and x = 6 is the difference in y values over the difference in x values.
1866.24 - 368.64 = 1497.6
6 - 2 = 4
1497.6 / 4 = 374.4
