Math Problem Statement

find the range given the following domain. f(x)=-5x+3; {-2,-1,0,1,2}

Solution

To find the range of the function f(x)=5x+3f(x) = -5x + 3 for the given domain {2,1,0,1,2}\{-2, -1, 0, 1, 2\}, we will evaluate the function at each value of xx.

  1. For x=2x = -2: f(2)=5(2)+3=10+3=13f(-2) = -5(-2) + 3 = 10 + 3 = 13

  2. For x=1x = -1: f(1)=5(1)+3=5+3=8f(-1) = -5(-1) + 3 = 5 + 3 = 8

  3. For x=0x = 0: f(0)=5(0)+3=0+3=3f(0) = -5(0) + 3 = 0 + 3 = 3

  4. For x=1x = 1: f(1)=5(1)+3=5+3=2f(1) = -5(1) + 3 = -5 + 3 = -2

  5. For x=2x = 2: f(2)=5(2)+3=10+3=7f(2) = -5(2) + 3 = -10 + 3 = -7

Thus, the range of the function for the given domain {2,1,0,1,2}\{-2, -1, 0, 1, 2\} is:

{13,8,3,2,7}\{13, 8, 3, -2, -7\}

Would you like further details or have any questions?

Here are 5 related questions to explore:

  1. What is the slope of the function f(x)=5x+3f(x) = -5x + 3?
  2. How does changing the domain affect the range of a function?
  3. How would the range change if the function was f(x)=5x+3f(x) = 5x + 3 instead?
  4. What is the meaning of the y-intercept in the function f(x)=5x+3f(x) = -5x + 3?
  5. How can you graph the function based on the calculated points?

Tip: In linear functions, the slope determines how fast the function increases or decreases as xx changes.
