Answer 2

Answer:

Option A- (2,12)

Step-by-step explanation:

Given,

the function f(x)=2(3)x

                  ∴ f(x)=6x

The function begins with the point (1,6)

we can solve these type of questions in two methods:

Method 1:

Hit and trial

assume a value of x and substitute the value in the function f(x) and get the ordered pair, that is, (x,f(x))

f(x) = 6x

let x=2 (the next point to 1)

then f(x)= 6×2=12

f(x)=12

Hence the next point is (2,12)

Method 2:

Option checking

With help of options provided, check the ordered pair with the relation of the function provided.

In the options provided to us, Option A- (2,12) is the only one that satisfies the given function.

Hence the next point is (2,12)
