Use the distributive property to multiply the two sets of parentheses. You should have learned this in Algebra 1.
f(x) = (3/4)ˣ - 4
As x gets really negative (3/4)ˣ grows positively without bound (because it's (4/3)⁻ˣ and 4/3 > 1).
As x gets really positive (3/4)ˣ tends to zero but never quite gets there.
So (3/4)ˣ > 0 for all x
So f(x) > 0 - 4 for all x
Answer: { y | y > -4 }, first choice
Answer: 192 people
Step-by-step explanation:
We can set up a ratio.
Let x be the number of men working in the company.
We can cross umltiply.
360 = 5x
x = 72 men.
Therefore, the total number of employees = 120 women + 72 men
= 192 people.

Calculate the area
The area is calculated as thus:
|x-4|=1
|x-4|-1=0 absolute values have 2 equations in them
x+4-1=0, x=3
x-4-1=0, x=5
