Write down the coefficient of \( x \)

To find the coefficient of \( x \), you need to look for the term in a polynomial or expression that contains \( x \). The coefficient is simply the numerical factor that is multiplied by \( x \). For example, in the expression \( 3x^2 + 5x - 7 \), the coefficient of \( x \) is \( 5 \). If the term was \( -2x \), then the coefficient would be \( -2 \). Remember, if no number is explicitly written with \( x \) (as in \( x \) itself), the coefficient is \( 1 \). In mathematics, recognizing coefficients is vital, as they help determine how steeply a line rises or falls in graphical representations. They also play a crucial role in solving equations and understanding functions' behavior, so every time you see \( x \), take a moment to spot that trusty coefficient!
