Answer:

Step-by-step explanation:

The ratio of the number of fiction books is 9:4

the difference between the number of fiction and nonfictionn is 245

so if the number of fiction books = 9x

then the number of nonfiction books = 4x

then difference = 9x-4x = 5x

the difference is given 245

then 5x= 245

x= $\frac{245}{5}$ =49

number of fiction books =49×9=441

number of nonfiction books =49×4=196

The function f is defined by f(x)=2x^2-4.<br> Find f(-x)

Vedmedyk [2.9K]

First of all, since all powers of x in this function are even, the entire function is even. Thus, using -x as input doesn't change the function. Thus, f(-x)=2x^2-4.
