Write the function in vertex form. {eq}\displaystyle y = - x^2 - 3x - 6 \\y = \boxed{\space} {/eq} Equation of a Parabola in Vertex Form The equation of a parabola can be expressed in numerous ways. In a general sense, a standard form of a parabola is given b...
y=x2+2x+2 and 2y2+4y−2x+1=0 Parabola:The vertex form of a parabola gives us clear understanding of the parabola and its easy to compute its parameters from the equation itself. The vertex form of a parabola which opens horizontally and vertical...
x-intercepts are OBVIOUSLY -3 and 5/2 because those x values make y=0 (also called roots, or zeros of function) vertex's x value is the average of the x-intercepts. then plug hat average in for x to get y-coordinate. [there's also the formula xvertex = -b/(2a) if quadratic ...
The intercept form is, in this case, {eq}(x~-~5)(x~+~1) {/eq}. {eq}y~=~2x^2~+~6x~+~6 {/eq} Applying the distributive property to {eq}2(x~+~1)(x~+~2) {/eq} one obtains the previous expression, meaning that it is the factoring of the above quadratic function. How...
