Answer:

  y = (x -3)² -2

Step-by-step explanation:

The vertex form of the equation of a parabola is ...

  y = a(x -h)² + k

for vertex (h, k) and vertical scale factor "a".

Your graph shows the vertex to be at (x, y) = (3, -2). Note that one unit either side of the vertex, the graph goes up one unit. The number of vertical units difference from the vertex is the value of "a", so it is 1 for this parabola.

That means the equation is ...

  y = 1·(x -3)² -2

or, more simply, ...

  y = (x -3)² -2 . . . . . . . matches the 3rd choice

_____

Please note that if "a" is negative, the parabola will open downward. This one opens upward, so you can immediately reject the first two answer choices.

1. One face is 5.1*2.5=12.75 un^2, one is 8.5*2.5=21.25, one is 6.8*2.5=17, and two are 1/2*6.8*5.1, so both are 34.68. Total is 85.68, rounded to 85.7 cm^2. (C)

2. The area of the circles is 2(π*2^2), which is about 25.1. The rectangle's area can be found as 2π*2*3, which is about 37.7. The total is rounded to 62.8 m^2 (D)

3. Rectangular faces: 3.6*1.8=6.48, 8.5*1.8=15.3, 7.7*1.8=13.86

Triangles: 2(1/2(3.6*7.7))=27.72

Total: 63.36, round to 63.4 km^2 (B)

What are the intercepts of this function f(x)=-8x+4
Sidana [21]

Answer:

Step-by-step explanation:

to find the x-intercept:

Make y=0

0=-8x+4

8x =4

x=4/8

x=1/2

to find y-intercept:

Make x=0

y=-8(0) +4

y=4

Hope this helps!
