1 answer

To find the values of the functions \( f(x) \) and \( g(x) \), we'll substitute the given inputs into their respective equations.

Question 1: The function \( f(x) \) is defined as: \[ f(x) = x^2 - 5 \]

To find \( f(4) \): \[ f(4) = 4^2 - 5 \] \[ f(4) = 16 - 5 \] \[ f(4) = 11 \]

So, \( f(4) = 11 \).


Question 2: The function \( g(x) \) is defined as: \[ g(x) = 7x + 10 \]

To find \( g(-3) \): \[ g(-3) = 7(-3) + 10 \] \[ g(-3) = -21 + 10 \] \[ g(-3) = -11 \]

So, \( g(-3) = -11 \).


Final Answers:

  1. \( f(4) = 11 \)
  2. \( g(-3) = -11 \)
