Answer:
Equation of the parabola: or
Vertex form:
Intercept form:
Step-by-step explanation: hope this helps please give brainlieat!
so.. what is the coefficient "a"?
well
now, we know, another point on the graph, besides the vertex, we know a y-intercept, that is, 0, -30, that simply means when x = 0, y = -30
now, getting the x-intercepts, is just the zeros, or solution to the quadratic
notice, "y" is 0 on both cases, because, is an x-intercept, or a zero, and when the graph touches the x-axis, "y" is zero
Answer:
0
Step-by-step explanation:
-7=2x-7
+7 +7
0=2x
x=0
Answer:
Step-by-step explanation:
That is a factorial, which is calculated by multiplying 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 (which is a really BIG number!) 40,320 to be exact!
