The rule for given function is: [tex]f(x) = 14x-74[/tex]
Step-by-step explanation:
The general form of a linear function is:
[tex]y= mx+b[/tex]
Here
m is the rate of change of function and b is the y intercept
Rate of change of function is given by:
[tex]m = \frac{Change\ in\ y}{Change\ in\ x}\\m = \frac{-32-(-46)}{3-2}\\m = \frac{-32+46}{1}\\m = 14[/tex]
Putting the value of rate of change in the general form
[tex]y = 14x + b[/tex]
to find the value of b, putting a pair of input and output in the function
Putting x=2 and y = -46
[tex]-46 = 14(2)+b\\-46 = 28 +b\\b = -46-28\\b = -74[/tex]
Putting b=-74 in function
[tex]y = 14x-74[/tex]
Replacing y with f(x)
[tex]f(x) =14x-74[/tex]
The rule for given function is: [tex]f(x) = 14x-74[/tex]
