Math Problem Statement

the function of f is shown below

f(x) = 4x + 7

work out the value of f(10)

Solution

To find the value of f(10)f(10), we substitute x=10x = 10 into the given function f(x)=4x+7f(x) = 4x + 7.

f(10)=4(10)+7=40+7=47f(10) = 4(10) + 7 = 40 + 7 = 47

Thus, the value of f(10)f(10) is 4747.

  1. What is the value of f(0)f(0) for the same function?
  2. How would the function change if the constant term were altered?
  3. Can you express the function f(x)=4x+7f(x) = 4x + 7 graphically?
  4. What is the inverse of the function f(x)=4x+7f(x) = 4x + 7?
  5. How does the function behave for negative values of xx?

Tip: Functions like f(x)=4x+7f(x) = 4x + 7 are linear, meaning their graph is a straight line.
