Question
Find the vertex of the function. f(x) = Ix + 7I – 2
- (-2, -7)
- (2, -7)
- (-7, -2)
- (7, -2)
Hint:
We know that;
f(x) = aIx – hI + k
compare the given function
where; vertex is (h, k)
The correct answer is: (-7, -2)
f(x) = aIx – hI + k
Vertex is (h, k)
f(x) = Ix + 7I – 2
Vertex is (-7, -2)
