Answer:

3x² - 17

Step-by-step explanation:

f(x) = 3x +1

g(x) = x² - 6

f(g(x)) = f(x² - 6)

Now (x² - 6) is the (x) for function f.

=> f(x) = 3x +1 = 3(x² - 6) + 1 = 3x² - 18 + 1

=> 3x² - 17

AlekseyPX

Answer:

Z-value is what we called the number of standard deviations from the mean. 62% is 8% one standard deviation to the left, or a Z-value of -1. 94 is 24% to the right of the mean, or 3 standard deviations for a z-value of three. You can look on a Z-table to find the area between -1 and 3, which is .840 or 84%
