Tutorial Exercise
Find any intercepts.
y =x - 49x
Step 1
To find the y-intercepts, let x be zero and solve for y.
y = (0)3 - 49(0)
(Let x be zero.)
y = 0
Hence, the y-intercept is (x, y) = (0,0
0.0
).
Step 2
To find the x-intercepts, let y be zero and solve for x.
(0) = x - 49x
0 = x(x? - 49)
= x(x2 - 72)
= x(x - 7)(x + 7)
x = 0, 7
Step 3
Hence, the x-intercepts are (x, y) = (
), and (
). (Enter your answers from smallest to largest.)
