Graph 3/x^2-4. Then find the domain/range/VA

Question

astrophysics · Answer

$$f(x) = \frac{ 3 }{ x^2 }-4?$$ is this your equation, think of the parent function, which in this case is $$\frac{ 1 }{ x^2 }$$ it looks like |dw:1439265308847:dw| you can get this by simply making a table of values which you can do yourself. Once you have your parent function now we can do our transformations. $$y = \frac{ 3 }{ x^2 }$$ where the 3 should give you a scaling factor then afterwards add the -4, $$y = \frac{ 3 }{ x^2 }-4$$ where the -4 should give you a vertical translation of -4 units. If you're not comfortable at seeing it directly you can always make a table of values for each step, good luck!
