Answer:
y = 2(x + 3)² - 4
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Using the method of completing the square
y = 2x² + 12x + 14 ← factor out 2 from the first 2 terms
= 2(x² + 6x) + 14
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
y = 2(x² + 2(3)x + 9 - 9 ) + 14
= 2(x + 3)² - 18 + 14
= 2(x + 3)² - 4 ← in vertex form

Down because the slope is negative
Answer:
6.8
Step-by-step explanation:
Similar means the same shape but smaller. So we have to find the connection between 17 and 5. Which can be achieved by this equation
17/5=3.4
Now we apply the number 3.4 to find the length of PQ using the same side on the similar shape
2*3.4=6.8
