Question

What are the x- and y-intercepts of f(x) = x2 - 49?

Answer 1

Answer:

            x-intercepts:  (-7, 0) and (7, 0)

             y-intercept:  (0, -49)

Step-by-step explanation:

x-intercepts:  f(x) = 0

               x² - 49 = 0

                x² = 49

         x = -7    ∨  x = 7

Points:  (-7, 0)  and (7, 0)

y-intecept:   y = f(0)

f(0) = 0² - 49 = -49

Point:  (0, -49)
