Math Problem Statement

Write a linear function f with f(-10) = 4 and f(-2) = 4

Solution

A linear function has the general form:

f(x)=mx+bf(x) = mx + b

where mm is the slope and bb is the y-intercept.

Step 1: Find the Slope

The slope mm is given by:

m=f(x2)f(x1)x2x1m = \frac{f(x_2) - f(x_1)}{x_2 - x_1}

Substituting the given points (10,4)(-10, 4) and (2,4)(-2, 4):

m=442(10)=08=0m = \frac{4 - 4}{-2 - (-10)} = \frac{0}{8} = 0

Since the slope is 0, the function is a constant function:

f(x)=4f(x) = 4

Conclusion:

The linear function satisfying the given conditions is:

f(x)=4f(x) = 4

This means that for any value of xx, the function always outputs 4.
