The correct question is <span>What are the vertex and x-intercepts of the graph of the function given below? y = x</span>²<span>-2x-35
step 1 convert the equation in the vertex form y+35=x</span>²-2x y+35=(x²-2x+1-1) y+35+1=(x²-2x+1) y+36=(x-1)²------> equation in the vertex form
the vertex is the point (1,-36)
the answer Part a) is the vertex is the point (1,-36)
Part b) Find the x-intercepts we know that the x-intercepts is when y=0 so y+36=(x-1)² for y=0 (x-1)²=36 (+/-)(x-1)=√36-------> (+/-)(x-1)=6 (+)(x-1)=6------> x=6+1-----> x=7 (-)(x-1)=6-----> x=1-6-----> x=-5
the x-intercepts are the points (7,0) and (-5,0)
the answer part b) is the x-intercepts are the points (7,0) and (-5,0)
the total answer is the option <span>A. Vertex: (1, -36); x-intercepts: (7, 0) and (-5, 0)</span>
It could sometimes be proportional. The reasoning here is that if all the items have different prices it won't be, however if the items you are ordering all have the same price they will be!
