When the measure of angle A increases im the trianes, the measure of angle A on line p also increases. This is angle A in the triangle and angle A on line p are equivalent to each other. Hence, if there is an increase to one of the angle As then there is also an increase to the other.
F(x) = g(x) 3(2) - 4 = (2)² - 2 6 - 4 = 4 - 2 2 = 2 I just substituted all the values in the domain to see which one would work. That's not really the quickest way but that's the only way I know
