(a) f + g (b) f – g (c) f*g (d) f/g

Please show all of your work.

f(x) = x + 5

g(x) = 5x^2+15x-3

**Steve**, Wednesday, January 4, 2012 at 4:32pmjust substitute f and g as needed

f(x) + g(x) = (x+5) + (5x^2 + 15x - 3)

= 5x^2 + 16x + 2

f(x) + g(x) = (x+5) - (5x^2 + 15x - 3)

= -5x^2 - 14x + 8

f(x) * g(x) = (x+5) * (5x^2 + 15x - 3)

= 5x^3 + 20x^2 + 72x - 15

f(x) + g(x) = (x+5) / (5x^2 + 15x - 3)

2nd and 4th lines should read f(x)-g(x) and f(x)/g(x)
