Trig Help!

[HunkyBruce]

I have to work quickly and I need help figuring out this question. The equation is: g(x) = (x - 3)^2 + 7. I have to graph the range of "g" on a number line. Can anyone help me? I have no idea where to start..

I guess the first question I have for you is do you know how to find the range of this equation?

 

[HunkyBruce]

No, I don't know how to do that.

In layman's terms, the range of an equation are all the set of all possible values that the function can obtain and it's usually expessed from the smallest to the largest values. So for this equation, what is the smallest value y can be and what is the largest value y can be?

 

[HunkyBruce]

smallest is -3 and largest is 7? I'm not sure

Okay then - open your textbook (or use google) to find the definition of the term "range of a function".

While at it get familiar with the term "domain of a function" too.

Then tell us what you found.

Ok. Thank you.

Bruce, are you familiar with parabolas?
