Consider the following function: f(x) = 5x^{2/5} - 2x. Find the x-intercept(s) of the function. Consider the function f (x) = {x + 1} / {x + 3}. a) Find any x-intercepts. b) Find the y-intercepts. Find the two x-intercepts of t...
The vertex of a quadratic function is the vertex of the graph of that function. Given a quadratic function in vertex form, f(x) = a(x-h^2)+k, the vertex is located at the point (h,k). It is the point through which the axis of symmetry passes. Knowing how to find the vertex ...

Step 1:Find all intercepts. The {eq}x {/eq}-intercept(s) are points {eq}(a,0) {/eq} where the graph of the function touches the {eq}x {/eq}-axis. The {eq}y {/eq}-intercept is a point {eq}(0,b) {/eq} where the graph of the function touc...
Some functions may also havex-intercepts:for a functiong(x), these are values ofxfor whichg(x) = 0. In other words, anx-intercept is a solution to the equationg(x) = 0. The values ofxthat satisfy this equation are also calledrootsorzeroesof the function. A function may have ...
