The answer should be D.
Hope it helped you.
g(x) = -(x + 1)^2 - 3
Let's simplify this equation
g(x) = -(x^2 + 2x + 1) - 3
Distribute the negative sign
g(x) = -x^2 - 2x + 1 - 3
Combine like terms
g(x) = -x^2 - 2x - 2
The value of a = -2 and this value is LESS THAN 0
Answer:
A standard normal distribution refers to a normal distribution with a mean of 0 and a standard deviation of 1. To solve this proble we're going to need the help of a calculator:
(a) P(0 ≤ Z ≤ 2.38) = 0.4913
(b) P(0 ≤ Z ≤ 1) = 0.3413
(c) P(−2.70 ≤ Z ≤ 0) = 0.4965
(d) P(−2.70 ≤ Z ≤ 2.70) = 0.9931
(e) P(Z ≤ 1.62) = 0.9474
(f) P(−1.55 ≤ Z)= 0.9394
(g) P(−1.70 ≤ Z ≤ 2.00) = 0.9327
(h) P(1.62 ≤ Z ≤ 2.50) = 0.0464
(i) P(1.70 ≤ Z) = 0.0445
(j) P(|Z| ≤ 2.50) = 0.9876
All values are verified! ✅
