WebApr 30, 2024 · Solution: To graph the function, we will first rewrite the logarithmic equation, y = log1 3(x), in exponential form, (1 3)y = x . We will use point plotting to graph the function. It will be easier to start with values of y and then get x . y. (1 3)y = x. WebThe Function Grapher can help you. Enter the equation as "y= (some function of x)". You can use zoom to find important points. If you can't write the equation as "y= (some function of x)", you can try the Equation Grapher, where you enter equations like "x^2+y^2=9" (meaning x2+y2=9 ). But remember they are just a help!

WebFeb 10, 2024 · Find the range on the graph. Now, look at the y-coordinates on the graph and find the lowest point at which the graph touches a y-coordinate. In this case, the lowest y-coordinate is at the vertex, -5, and the graph extends infinitely above this point. This means that the range of the function is y = all real numbers ≥ -5. WebSeveral things are apparent if we examine the graph of f(x) = 1 x. On the left branch of the graph, the curve approaches the x -axis (y = 0) as x → – ∞. As the graph approaches x = 0 from the left, the curve drops, but as we approach zero from the right, the curve rises.

WebMar 31, 2024 · 2. Set the denominator equal to zero for fractions with a variable in the denominator. When finding the domain of a fractional function, you must exclude all the x-values that make the denominator equal to zero, because you can never divide by zero. So, write the denominator as an equation and set it equal to 0. [2] WebGraph the equation. y=-2 (x+5)^2+4 y = −2(x + 5)2 + 4 This equation is in vertex form. y=\goldD {a} (x-\blueD h)^2+\greenD k y = a(x − h)2 + k This form reveals the vertex, (\blueD h,\greenD k) (h,k), which in our case is (-5,4) (−5,4). It also reveals whether the parabola opens up or down. Since \goldD a=-2 a = −2, the parabola opens downward.
