If f(x) = 3x^2 - 2x + 5, find f(-2)
A. f(–3) = 3
B. f(–3) = 6
C. f(–3) = 9
D. f(–3) = 12

Step-by-step explanation:

hello :

If f(x) = 3x² - 2x + 5,

f(-2)=3(-2)² - 2(-2) + 5=12+4+5=21

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
