Answer:
D. f(x) = x + 1.
Step-by-step explanation:
f(x) = x + 1 because:
0 = -1+1
1 = 0 + 1
2 = 1 + 1
3 = 2 + 1
The answer is C because 4 + 15 = 19.
Obtuse: b^2 + c^2 > a^2
Right: b^2 + c^2 = a^2
Acute: b^2 + c^2 < a^2
A^2 + B^2 + c^2 - 2bc*cosA
As (A), is an Obtuse cos A is Negative say 2bccosA = - k then;
a^2 = b^2 + c^2 + k
a^2 > b^2 + c^2
So, your Answer would be (B)
