Best ResponseYou've already chosen the best response.0@kkailyn C is actually the incorrect answer. As you can see from your chart, at x = (1), the function is at 3, and at x = (0), the function is at 2. Since the function is going from 3 to 2, the function is actually increasing between x = (1) and x = (0).

Best ResponseYou've already chosen the best response.0ok well this one i already have answered it but im not quite sure im right. Two quadratic functions are shown. Function 1: f(x) = 2x2 − 8x + 1 Function 2: x g(x) −2 2 −1 −3 0 2 1 17 Which function has the least minimum value and what are its coordinates? Function 1 has the least minimum value and its coordinates are (0, 1). Function 1 has the least minimum value and its coordinates are (2, −7). Function 2 has the least minimum value and its coordinates are (0, 2). Function 2 has the least minimum value and its coordinates are (−1, −3).

Best ResponseYou've already chosen the best response.0ok now the last one. The function f(x) = −x2 + 50x − 264 models the profit, in dollars, a yoga studio makes for selling monthly memberships, where x is the number of memberships sold and f(x) is the amount of profit. Part A: Determine the vertex. What does this calculation mean in the context of the problem? Part B: Determine the xintercepts. What do these values mean in the context of the problem?

Best ResponseYou've already chosen the best response.0You can see from the chart that function #2 has a minimum value of (1,3). We know this because the x values on either side of 1, 2 and 0, provide us with y values that are greater than 3. Now that we know what the minimum value is for function #2, we need to find the minimum for function #1. We can do this by using the first bit of the quadratic formula (b/2a). Plugging in function #1 gives us (8/4) or 2. This represents the x value of the vertex. Plugging 2 into function #1 gives us an answer of 7, or a vertex of (2,7). Now that we know both vertices, we can see that, since 7 is smaller than 3, function #1 has the least minimum value, occurring at (2,7)

Best ResponseYou've already chosen the best response.0Since you know the quadratic formula, the first part is relatively simple. Once again, using the first bit of the quadratic formula (b/2a) we can find the x value of the vertex. Let's do that... (50/2) = 25. This is the x value so let's plug it into the equation and find the corresponding y value. f(25) = 25^2 + 50*25  264 = 625 + 1250  264 = 1611. The vertex can be found at (25,1611)
