To find the value of f(x) = x² + 4 at certain points, you simply need to substitute the given values into the function. a) For f(5): - Substitute x = 5 into the function f(x) = x² + 4. - f(5) = 5² + 4 - f(5) = 25 + 4 - f(5) = 29 Therefore, f(5) = 29. b) For f(-5): - Substitute x = -5 into the function f(x) = x² + 4. - f(-5) = (-5)² + 4 - f(-5) = 25 + 4 - f(-5) = 29 Hence, f(-5) = 29.
