Answer by JKismyhusbandbae: So this is really simple. You are probably making this out harder than it needs to be. Consider the set of ordered pairs {(-1,0), (4,-5), (6,-6), (9,11), (10,14)}. This set of ordered pairs is a function because for each value of x there is one and only one y-value. This means that the x value never repeats. Therefore any function is a function when the x value never repeats.
Looking at the table we want to find all it's ordered pairs: (0,4), (1,2), (2,3), (3,9), (4,1).
F(2) is 3 so when x equals 2.
So the ordered pair is (2,3) 2 is the x value and the f(2) is 3.
Simplify it or what if so then the answers would be r>48
y<(line under it)6
Answer:
C. 7
Step-by-step explanation:
Advertising is x and revenue is y
(0,2)(2,6)
slope = (6 - 2) / (2 - 0) = 4/2 = 2
y = mx + b
slope(m) = 2
(0,2)...x = 0 and y = 2
now we sub and find b, the y int
2 = 2(0) + b
2 = b
so ur equation is : y = 2x + 2
spends 10 mill on advertising.....so x = 10
y = 2x + 2
y = 2(10) + 2
y = 20 + 2
y = 22.....so the revenue (y) of the company is 22 (million)
1/2X+4=X-4
1/2X+8=X
8=1/2X
16=X
(Pick one of the equations )
y=1/2X+4
y=(1/2)(16)+4
y=12
point: (16,12)
