Find the quadratic function represented by the following graph.​

Answer:

f(x) = (-3/4)x^2 + 3

Step-by-step explanation:

First, look at the vertex to see if it intersects the y-axis. It does, which is good, because it makes your job a lot easier by making your equation to fill out y = ax + b. Your b is the y value of your vertex, which in this case is 3. Then, your a is the amount you're multiplying plain old x^2 by to get your values (before adding 3). Because the graph is pointing down, you know right away that it's going to be negative. Also, going to the left or right by 2 (the points you are given) from the vertex gives you a result of going down 3. Normally this would mean you move up by 4 (again, from the vertex), so what do you need to multiply 4 by to get -3? -3/4, so that's your a. This makes your equation (y OR) f(x) = (-3/4)x^2 + 3

I hope I didn't make any mistakes reading your graph! I had a bit of difficulty with it unfortunately.

Georgia [21]

Answer:

5

Step-by-step explanation:

A=a+b/2 x h

4 = a

5 = b

8 = h

4 + 5 / 2 = 4.5

4.5 x 8 = 36

So the other base length is 5

Answer:

The slope is 70

The slope represents the speed of your car

Step-by-step explanation:

The slope is 70, y = mx + c, where m is the slope

The slope represents the speed of your car

speed = distance/time

speed x time = distance

As y represents the distance you travel, x is the time, slope is the speed, you get the distance travelled.
