What is the y-intercept of the graph of y -2x2-4x-3?
-3
Can you show me how to graph y -x2 - 4x - 3?
y = -x2 - 4x - 3. The constant, 3, tells us where the graph would hit the y-axis. In this case, it would hit the y-axis at -3. Solving the equation y = -(x2 + 4x + 3) ; y=-(x+3)(x+1) Therefore hits the x-axis at -3 and -1. Since it's a parabola (x2), the graph can either start from the top, or from the bottom. An equation starting with ax2 will start from the top, and an equation with -ax2 will start from the bottom. So therefore, the graph starts from the bottom of the page, goes from -3 and -1 on the x-axis and intercepts the y-axis at -3.
What is slope y-intercept of 4x-2y equals 3?
4x-2y = 3 -2y = -4x+3 y = 2x-1.5 in slope intercept form
X intercept of 4x plus 2y equals 6?
For 4x + 2y = 6The X intercept is 1.5The Y intercept is 3
What is x2 plus 4x plus 4 equals 25?
x2+4x+4 = 25 x2+4x+4-25 = 0 x2+4x-21 = 0 (x+7)(x-3) = 0 x = -7 or x = 3
