1.8. Zeroes and Intercepts of Functions http://www.ck12.org
- Are there any functions without ay-intercept? Explain.
- Are there any functions without anx-intercept? Explain.
- Explain why it makes sense that anx-intercept of a function is also called a “zero” of the function.
Determine the intercepts of the following functions using algebra or a graph.
13.h(x) =x^3 − 6 x^2 + 3 x+ 10
14.j(x) =x^2 − 6 x− 7
15.k(x) = 4 x^4 − 20 x^3 − 3 x^2 + 14 x+ 5
