Complementary Angles:
Two angles whose measures add to 90º.
Basically, together they make a right angle.
Supplementary Angles:
Two angles whose measures add to 180º.
Basically, together they form a straight line.
Answer:
(f + g)(3) = 9
Step-by-step explanation:
f(x) = x² + 1
g(x) = x - 4
Thus:
(f + g)(x) = (x² + 1) + (x - 4)
(f + g)(x) = x² + 1 + x - 4
(f + g)(x) = x² + x - 3
Therefore, to find (f + g)(3), plug in the value of 3 into the equation:
(f + g)(3) = (3)² + 3 - 3
(f + g)(3) = 9 + 3 - 3
(f + g)(3) = 9
