What is the vertex of f(x) = |x + 8| - 3?
(-8, -3); (-8, 3); (8, -3); (8, 3)
Solution:
f(x) = |x + 8| – 3 [Given]
Standard equation of a curve in vertex form is
f (x) = a |x - h|2 + k
Where (h, k) is the vertex of the curve. Here a = 1.
Here we need to find h and k.
f(x) = |x + 8|2 – 3
It can be written as
f (x) = |x - (-8)| + (-3)
Comparing it with the standard form
(h, k) = (-8, -3)
Therefore, the vertex is (-8, -3).
What is the vertex of f(x) = |x + 8| -3?
(-8, -3); (-8, 3); (8, -3); (8, 3)
Summary:
The vertex of f(x) = |x + 8| - 3 is (-8, -3).
