Answer:
The x-intercept is the point where the graph crosses the x-axis; it can be found by setting y = 0 and solving for x.
The y-intercept is the point where the graph crosses the y-axis; it can be found by setting x = 0 and solving for y.
1) g(x) = (x + 5)⁴
- y-intercept: g(x) = (0 + 5)⁴ → (0, 625)
- x-intercept: 0 = (x + 5)⁴ → (-5, 0)
2) f(x) = 7 - x⁴
- y-intercept: f(x) = 7 - 0⁴ → (0, 7)
- x-intercept: 0 = 7 - x⁴ → (±
, 0)
3) h(x) = ¼(x - 3)⁴
- y-intercept: h(x) = ¼(0 - 3)⁴ → (0,
) - x-intercept: 0 = ¼(x - 3)⁴ → (3, 0)
