Step-by-step explanation:
g(f(x)) = f(x) substituted in g(x)'s function.
g(3x^2 - x - 8) = 3x^2 - x - 8 + 5 = 3x^2 - x - 3.
Good question I’m having trouble with this but I hope someone understands this
The temperature at the beginning of the day was 6.2°F
Let x represent the temperature at the beginning of the day.
Since, the temperature of a city doubles during the day, and then decreases by 14.1ºF after the sun goes down, hence:
Temperature at end of day = 2x - 14.1
Also, the temperature at the end of the day is −1.7°F, hence:
2x - 14.1 = -1.7
2x = 12.4
x = 6.2°F
The temperature at the beginning of the day was 6.2°F
