Write the domain and range of the function f(x)=3x+5

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)

Which function has the domain x> -11

`if you have a set of parallel lines a and b cut by transversal x, if angle 1 = 167 degrees, what is angle 4 and why. also what is the measure of angle 5 and why? you need to use the names of the angle relationship and explain. ''.
