The functions f(x) = -(x+4) +2 and g(x) =(x-2)^2 -2 have been rewritten using the completing the square method. Apply your knowl
rewona [7]

Answer:

g(x) = (x-2)^2 -2

If we compare this function with the vertex form we see that:

a = 1, h =2, k =-2

So then the vertex would be (h,k)=(2,-2)

And since the value for a is positive we know that the parabola open upward. We don't have a maximum defined since open upwards and the minimum point correspond to the vertex on this case (2,-2).

f(x)= -(x+4)^2 +2

If we compare this function with the vertex form we see that:

a=-1, h =-4, k = 2

And since the value for a is negative we know that the parabola open downward. We don't have a minimum defined since open downwards and the maximum point correspond to the vertex on this case (-4,2).

Step-by-step explanation:

We need to remember that the standard form for a parabola is given by the following equation:

y = ax^2 + bx +c

And the vertex form is given by this formula:

y = a(x-h)^2 +k

And we want to find the vertex and if we have a maximum or minimum for each function. Let's begin with g(x)

g(x) = (x-2)^2 -2

If we compare this function with the vertex form we see that:

a = 1, h =2, k =-2

So then the vertex would be (h,k)=(2,-2)

And since the value for a is positive we know that the parabola open upward. We don't have a maximum defined since open upwards and the minimum point correspond to the vertex on this case (2,-2).

For the function f(x) we assume that we have the following equation:

f(x)= -(x+4)^2 +2

If we compare this function with the vertex form we see that:

a=-1, h =-4, k = 2

And since the value for a is negative we know that the parabola open downward. We don't have a minimum defined since open downwards and the maximum point correspond to the vertex on this case (-4,2).

Part 1
Let:
y be the total cost
x be the number of tickets
a be fair admission

Since the fair charges $1.25 per ticket, the equation of the line would look like:

y = 1.25x + a

Since Johnny spent $43.75 and bought 25 tickets, we find a by replacing y with 43.75 and x with 25:

43.75 = 1.25×25 + a

Now solve for a

43.75 = 31.25 + a
43.75 - 31.25 = a
a = 12.50

Going back to the first equation:

y = 1.25x + 12.50


Part 2:
a) Let (9,8) be (x1,y1) and (4,-12) be (x2,y2)
The formula for slope is:
m =  \frac{y2 - y1}{x2 - x1}  \\ m =  \frac{ - 12 - 8}{4 - 9}  \\ m =  \frac{ - 20}{ - 5}  \\ m = 4
b) For the point-slope equation, I'll use (9,8)
Using the formula:
y - y1 = m(x - x1) \\ y - 8 = 4(x - 9)
c) For the slope-intercept form, we solve for y in the point-slope formula:
y - 8 = 4(x - 9) \\ y = 4x - 36 + 8 \\ y = 4x - 28
