Answer:
Normally, sequences don't go behind 1, but let's see for this one.
f(-1) = 1
Step-by-step explanation:
Let's sub for -1 in x.
f(-1) = 2(-1) + 3.
f(-1) = -2 + 3
f(-1) = 1

Answer:
1.28
Step-by-step explanation:
Given that a sample of 1500 computer chips revealed that 55% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 53% of the chips do not fail in the first 1000 hours of their use.

(Two tailed test for testing sample proportion with population proportion)
Std error of proportion assuming p = 0.53 is

p difference = 0.02
Z= test statistic = p diff/std error = 1.2775~1.28
