By looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.
First factor 175:
1, 5, 5, 7
Now that we know the factors of 175, combine common factors:
1, 5², 7
Hope this helps!
We need to know the definition of the "combined function" h(x). I'm going to guess--by looking at answers--that the function is

making it

This function is undefined wherever the denominator is equal to 0 (division by zero is undefined). Factor the denominator.

The two values of x that make the denominator 0 are 3 and -3, otherwise written

The area of the rectangle is simply width times length.
Hence, A = w*l = (6/5)*12 = 72/5 = 14.4 square inches (ANSWER)
