**How do you find the range of a function algebraically y**

Determine whether the points on this graph represent a function. Now, just as a refresher, a function is really just an association between members of a set that we call the domain and members of the set that we call a range.... A function is linear if one variable is directly proportional to the other.

**Identify a function from a graph LearnZillion**

The x intercepts occur when the function value equals zero. We don't need to find the zeros; all we need is the number of zeros, which can be obtained by finding the discriminant. We don't need to find the zeros; all we need is the number of zeros, which can be obtained by finding the discriminant.... Continue until you are convinced that, in all cases, the graph of the given function f is concave up where the derivative f ' (the slope of the tangent) is an increasing function, and concave down where the derivative f ' is a decreasing function.

**SOLUTION Without graphing tell how many x-intercepts y**

30/07/2015Â Â· Please feel free to share my resources with those in need or let me know if you need any additional help with your math studies. I am a true educator and here to help you out. I â€¦... Since we will be graphing (x, y) points, though, we will do our thinking with the 'y = mx + b' form for a while. When the function for a line is expressed this way, we call it the 'slope-intercept form' .

**How do you find the range of a function algebraically y**

One of the neat things about functions is that we know something is a function if each x has exactly one y but sometimes you are not given the points, you are not given numbers, all you are given is a funny graph. So what I want to talk about here is how you can tell that something is a function just based on the graph and you'll see it's actually pretty easy. It's using what's called the... Similar Questions. Algebra. Graph y=5^x and y=log_5 x on a sheet of paper using the same set of axes. Use the graph to describe the domain and range of each function.

## How To Tell If Something Is A Function Without Graphing

### In general, if the graph does not pass the Horizontal Line Test, then the graphed function's inverse will not itself be a function; if the list of points contains two or more points having the same y-coordinate, then the listing of points for the inverse will not be a function.

- While the tangent line is a very useful tool, when it comes to investigate the graph of a function, the tangent line fails to say anything about how the graph of a function "bends" at a point. This is where the second derivative comes into play
