You can put this solution on YOUR website!
+f%28x%29+=+%28-3x%2B5%29%2F%287x%2B4%29+
To find f(x+h) simply plug in "x+h" wherever you see an "x":
+f%28x%2Bh%29+=+%28-3%28x%2Bh%29%2B5%29%2F%287%28x%2Bh%29+%2B+4%29+
There's not much else to do with it, based on the information you have given. Nothing is going to cancel and no further simplification can be made. Is that all they wanted?
f(x) is not defined when the denominator is 0, and that occurs when 7(x+h) + 4 = 0.
