Hello :
y = 3x2 + 24x - 1
= 3(x²+8x) -1
= 3 (x² +2(4)(x) +4²- 4² ) -1
= 3((x+4)² -16)-1
y = 3(x+4)² - 49
the line of symmetry is : x= - 4

There is no graph to support the statement and so, this invisible graph is misleading :)

Answer:

y = -9x + 12

Step-by-step explanation:

first find the slope

m= 3 - 12

1 - 0

m = -9

y = mx + b

y = -9x + 12

(the 12 is the y intercept and is given in the question so there is no need to solve for it)

Answer:

x = 0 AND x = -1

Step-by-step explanation:

You find the solution by finding where the two graphs meet. Then you can pull the x-coordinate off the points of intersection which is at 0 and -1
