What are the values of x for which the denominator is equal to zero for y = x+3/x²+4x x² + 4x

X = -4

x=0, x=-4

no points of discontinuity

x = 0,X = 4

F(x)= 1/x-4, g(x)=4x+1/x a. use composition to prove whether or not the functions are inverses of each other. b. express the domain of the compositions using interval notation.

Find the exact value of each of the following. in each case, show your work and explain the steps you take to find the value. (a) sin 17π/6 (b) tan 13π/4 (c) sec 11π/3

When 142 is added to a number the result is 64 more times the number my options are 35 37 39 41
