Answer 1
Answer:

Answer:

The function through which given point passes is f(x) = 24 x - 12 .

Step-by-step explanation:

Given as :

The points are

x_1 , y_1 = 1 , 12

x_2 , y_2 = 2 , 36

now, slope of the line

Let The slope of line = m = (y_2-y_1)/(x_2-x_1)

Or, m = (36 - 12)/(2-1)

Or, m = 24

So The slope of line = m = 24

Now, equation of line in point-slope form

y - y_1 = m × (x - x_1 )

Or, y - 12 = 24 × (x - 1 )

or, y - 12 = 24 x - 24

or, y = 24 x - 24 + 12

or, y = 24 x - 12

or , f(x) = 24 x - 12

So, The function through which given point passes is f(x) = 24 x - 12 . Answer
