What is the vertex of the parabola with the equation y=1/5x^2 + 2x - 8

Mathematics
1 answer:
bixtya [17]2 years ago
8 0

Answer:

(-5,-13)

Step-by-step explanation:

Find the vertex of the parabola y=1/5x^2+2x−8.  

In this equation a=15  and b = 2.  

x= -2/2(1/5) = -2/2/5 = -2/1 * 5/2 = -5

Substitute −5 into the equation y=1/5x^2+2x−8

y=1/5(−5)^2+2(−5)−8

y=5−10−8

y=−13

The vertex is (−5 , −13)

2. Create a linear function that has a rate of change of 3 and a solution at (6, 12).
Ksivusya [100]

Answer:

y = 3x - 6

Step-by-step explanation:

A linear function has the following format:

y = ax + b

In which a is the slope(rate of change) and b is the y-intercept, that is, the value of y when x = 0.

Rate of change of 3

This means that a = 3

So

y = 3x + b

A solution at (6, 12).

This means that when x = 6, y = 12. So

y = 3x + b

12 = 3*6 + b

b = -6

The linear function is:

y = 3x - 6
