Question

Write a liner function f with the given values
f(0) = -4; f(10) = -12
f(x)=

Answer 1

• f(x) = - x - 4

----------------------

Linear function is:

• f(x) = mx + b, where m- slope, b- y-intercept

Given points:

• f(0) = - 4 and f(10) = - 12

The first point represents the y-intercept, b = - 4.

Find the slope:

• m = (-12 - (-2)) / (10 - 0) = - 10/10 = - 1

The function is:

• f(x) = - x - 4
