Substituting α=5 back into the vertex form gives:(x−5)2=−(y−9)or(x−5)2=−y+9Thus, the new parabola is:y=−(x−5)2+9 Step 9: Find the intersection points with the x-axisTo find the x-intercepts (where y=0):0=−(x−5)2+9Rearranging gives:(x−5)2=...
y=a(x−p)(x−q) In this equation p and q are the x-intercepts, and a is some coefficient. Answer and Explanation: The information given in this problem is that the x-intercepts are -3 and 2, and the y-intercept is -6. The general form of a...Be...
We can use the same method to find the vertex by changing the form of the equation into the vertex form which is a(x−h)2+k, where (h,k) is the vertex. Answer and Explanation:1 The equation we have is −2x2+6x+1=0
