Input 1 2 3 4 output -8 -11 -14 -17 what is the rule

The function rule is:

Step-by-step explanation:

Using the given input/output values, we can take two pairs of input-output values for finding the rule.

The function is a linear function as the input and output are changing linearly.

Required pairs are:

(1,-8)  and (2, -11)

The general rule for linear function is:

m is the slope of the function calculated using the formula

Putting the values

Putting in equation

To find the value of b, putting (1,-8) in the equation

Putting the values

Hence,

The function rule is:

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
