y = 1/2x + 3
change x and y
x = 1/2y + 3
now find the value of y and that is inverse function
x - 3 =1/2 y
y = 2x- 6
f-(x) = 2x - 6
<u />
for both domain : ( - ∞ , + ∞ )
range f (x) : ( - ∞ , + ∞ ) - { 0 }
range f-(x) :( -∞ , +∞)
Answer:
Step-by-step explanation:
Anything between 91 degrees and 179 degrees. You can pick any between these two.
You must divide 2400 by 4 to find your answer. If you know 24/4, then it should be easy. 24 divided by 4 is 6, so add those 2 zeros and you should get 600 pennies for each student.
