If its even the f(x) = f(-x)
f(-x) = -x ((-x)^3 + x) = x^4 - x^2
f(x) = x^4 - x^2
So the function is even

Answer:
why stop this dude
Step-by-step explanation:
The rate of change:
( y2 - y1 ) / (x2 - x1) = ( 18 in - 12 in ) / ( 6 ft - 4 ft ) =
= 6 in / 2 ft = 3 in / 1 ft
Answer: D ) 3 inches up per foot across
Answer:
inverse f-1 (x) = x/18
Step-by-step explanation:
To find the inverse of a function f-1 (x), we represent f(x) by y or let f(x) = y
then make x the subject of the formula,
f(x) = 18x
Let f(x) = y
hence Y = 18x, make x the subject of the formula, do that by dividing both sides by 18,
Y/18 = x or x = Y/18
Interchanging or swapping x and y, therefore f-1 (x) = x/18
therefore, F(x) = 18x, the inverse f-1 (x) = x/18
