Which of the following would be an acceptable first step in simplifying the expression (cot x)/(1 - csc x) ?

cotx(1+csc x)/(1-csc x)(1+csc x)

cotx(1+csc x)/(1-csc x)(1+csc x)

Step-by-step explanation:

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
