First, what's 3 to the power of 8?
Then what's 3 to the power of 10
Now subtract them by each other for your answer
f(x) = 4x + 3
That's one-to-one, a linear function that will give a different f(x) for each different x.
For the inverse let's swap x and y and solve for y
x = 4y + 3
x - 3 = 4y
y = (x- 3)/4
That's the inverse,
Answer: (x- 3)/4, second choice
The domain and range of the inverse is all real numbers. It's two lines; I'll leave the graphing to you.
D. 5x = 45 because you are trying to find x, the number of tickets that must be sold to earn $45.
Y=-3x+4 is the correct answer
I believe that the correct answer is 72
Hope this helps!<3
