Question 762286
# 1


f(x) + 3*g(x) = 2x^2 - 3x +4 + 3*(x+3)


f(x) + 3*g(x) = 2x^2 - 3x +4 + 3x + 9


f(x) + 3*g(x) = 2x^2 + 13


So it's choice C

# 2


The range is the set of all possible outputs of a function. Basically it's the set of y values of each point.


The y values of (-1, -3), (9, -1), (-6, -9), (0, -4), (2, -1), (-2, -3) are: -3, -1, -9, -4, -1, -3


Toss out the duplicates to get:  -3, -1, -9, -4


and this is choice B (just in a different order, but order doesn't matter in a set)
