Did you know that in mathematics, finding the value of a function at a given point is an important concept? For instance, if we have the function f(x) = 4x^2 - x, we can find its value at -5 by replacing x with -5 in the function. Simply calculate the expression: f(-5) = 4(-5)^2 - (-5) = 4(25) + 5 = 100 + 5 = 105. Similarly, for the function g(x) = 4x + 4, we can find g(-7) by replacing x with -7: g(-7) = 4(-7) + 4 = -28 + 4 = -24. This helps us evaluate functions and understand their behavior at specific points!
