Question 385443: Any help with figuring out the steps to these problems will be greatly appreciated. I have a Functions test tomorow and I'm not feeling very confident. I pulled these out of a practice test.
If f(x)=-x+8 and g(x)=-5x+4 find h(x) when:
a) h(x)=f(x)+g(x)
b) h(x)=g(x)-f(x)
c) h(x)=f(x)x(times)g(x)

You can put this solution on YOUR website!
a)
h(x)=f(x)+g(x)
=-x+8+(-5x+4)
=-x+8-5x+4
=-6x+12
