What is the y-coordinate of the y-intercept of the function \(f(x)=x^3+3\)?

Answer and explanation

Correct answer: 3

Every point on the y-axis has \(x=0\). Thus, \(f(0)=0^3+3=3\), so the intercept point is \((0,3)\) and its y-coordinate is 3. Option B, 0, is the x-coordinate of the intercept, not its y-coordinate. Exam tip: To find a y-intercept, substitute \(x=0\).
