First write it in vertex form :-
y= a(x - 2)^2 + 3 where a is some constant.
We can find the value of a by substituting the point (0.0) into the equation:-
0 = a((-2)^2 + 3
4a = -3
a = -3/4
so our equation becomes y = (-3/4)(x - 2)^2 + 3
i think the answer is 35° because the triangles are congruent to each other
Answer: <em>$43.20</em>
Step-by-step explanation:
<em>First, we are going to take the price of the box lunch ($6.50)</em>
<em>Now we are going to multiply it by 5</em>
<em>$6.50x5=$32.50</em>
<em>Now we take the total cost of the trip and subtract it by $32.50</em>
<em>$248.50-$32.50=216</em>
<em>now divide 216 by 5</em>
<em>216/5</em>
<em>$43.20</em>
Domain:
Domain in interval notation: [0, infinity)
This is because the domain is the set of all allowed x inputs. In this case, x = 0 is the smallest and we include this endpoint. Any x value x = 0 or larger is part of the domain (since the graph stretches' on forever to the right)
--------------------------------------------------------------------
Range:
Range in interval notation: [2, infinity)
For similar reasoning as the domain, but now we consider the possible y output values. Here y = 2 is the smallest and we include it. Note the square bracket for interval notation means "include this endpoint". The curved parenthesis means "exclude this endpoint"
