Question

If f(x) is a linear function, what is the value of n?

Answer 1

13

Explanation:

Take any two corresponding values, say (3,7) and (9,16)

Calculate the gradient of the linear function

Gradient=[16-7]/[9-3]=9/6=3/2

find the equation or rule of the linear mapping

y-7=(3/2)(x-3)

y=3x-9+7

y=(3/2)x+5/2
