Let's say you took a step to the left and threw the ball higher in your backyard. ... Transformations of functions are the processes that can be performed on an existing graph of a function to return a modified graph. If [latex]k>0[/latex], the graph shifts upward, whereas if [latex]k<0[/latex], the graph shifts downward. If the number is between 0 and 1, the graph will be stretched. In other words, the graph will get wider. Find the Laplace transform of f(t) =\left\{\begin{matrix} 0, & t< 4 \\ t^2 -8t +22, & t \geq 4 \end{matrix}\right.

COMPLETE THE SENTENCE The graph of f(x) = (x + 2)3 is a _____ translation of the graph of f(x) = x3. Select a subject to preview related courses: You can also change the width of the graph by compressing or stretching the graph in the horizontal direction. We can transform graphs by shifting them, flipping them, stretching them, or shrinking them. The standard form and the general form are equivalent methods of describing the same function. They're usually in this form: f(x) = ax2 + bx + c. They will always graph into a curved shape called a parabola, which is a u-shape. The graph opens up if a ___ 0 and down if a __ _ 0. Improve your math knowledge with free questions in transformations of quadratic functions and thousands of other math skills. The magnitude of [latex]a[/latex] indicates the stretch of the graph.
