Answer:
#1. First label the function as y=f (x) #2. Express x as a function of y #3. Find all possible values of y for which f (y) is defined y y. #4. Element values of y by looking at the initial function f (x)
Step-by-step explanation:
It would be four. You can have four negative numbers and they will turn positive. For example, if you had -2 x -2 x -4 x -4 = 64. 64 would be positive because two negative numbers equal a positive number.
Answer:
It's linear!
Step-by-step explanation:
Just rewrite the equation as
y = x + 3
It has a slope and y-intercept, the most crucial parts that satisfy a linear equation. Since the slope is constant, it has to be linear.
tadah!
Answer:
Step-by-step explanation:
(x-5)2+8 = 92
