Answer: a) undercoverage.
Step-by-step explanation:

Thus, the sample will suffer from<u> undercoverage</u>.
Correct option: a) undercoverage.
Answer:C
Step-by-step explanation:it says from which means x-axis, (2,-7) moved left and right is (-5,-7) and "x-axis" as well bc the second option for the x coordinate is -7 that take 9 moves and not 7
(f.g)(x) = f (g(x))= f ( x^4+3)
= (x^4+3)^2 + 2 ( x^4+3) - 6
= x^8 + 9 + 6x^4 + 2x^4 + 6-6
= x^8 + 8x^4+9
