Feb 5, 2025 · The graph of a function f is the set of all its (input,output) pairs. When x is the input, then f(x) is the output. So, the graph is all points (x,f(x)), where x is in the domain of f.

Aug 24, 2022 · How to determine the value of a function \(f(x)\) using a graph. Go to the point on the \(x\) axis corresponding to the input for the function. Move up or down until you hit the …

Find the x -intercept and y -intercept on the (a) and (b) graphs in Figure 5.8.3. Find the x -intercept and y -intercept on the given graph. Find the intercepts of 2x + y = 8. Then graph the function …

The graph of yfx=() is mapped onto fx(+1) by a translation of 1 unit to the left. The curve for fx(2) is much steeper than for fx(). This is because the curve has been compressed by a factor of 2 …

The graph of a function looks like a curve above (or below) the \(x\)-axis, where for any value of \(x\) the rule \(y=f(x)\) tells us how far to go above (or below) the \(x\)-axis to reach the curve. …

Apr 18, 2025 · How to Use the Calculator. In the Function Input section, type your desired function using standard math syntax, such as x^2, sin(x), or log(x). Select a color to represent each …

Use this graph to sketch the graph of y = f ′ (x). Identify zero slopes, determine intervals of change, and sketch the slopes as f ′ (x). The function y = f (x) gives a graph showing how y …

It demonstrates how to sketch graphs from rules, derive rules from graphs, and calculate key features such as the gradient and x - and y - axis intercepts. Linear graphs are straight-line …
