X can be anything you want as long as it is not 1 or -7. If you have repeated x values with different y values, then it won't be a function.
Answer:
f^(-1)(x) = (x-b)/m or x/m - b/m
Step-by-step explanation:
f(x) = y = mx + b
To find the inverse function, interchange x and y and solve for y, i.e.
x = my + b
my = x-b
y = (x-b)/m = x/m - b/m
Answer:it increase
Step-by-step explanation:
If the o=2and e=30you look at the o and see that 45 is more then 2
Since 4 = $3.88
Then 1 = 3.88/4
= $ 0.97
Answer:
20x²+180x + 405
Step-by-step explanation:
Follow PEMDAS to know what you do first
square (2x + 9) by foiling
(2x+9) (2x + 9)
= 4x²+ 36x + 81
Multiply by 5
20x²+180x + 405
