Determine the axis of symmetry for the function f(x)=3(x+4)^2 -6

x = -4

Step-by-step explanation:

To determine the axis of symmetry, we need to find the vertex point.

Since the equation is already in vertex form, we can easily tell that the vertext point is (-4,-6)

We know the axis of symmetry is going to be vertical, and vertical lines are in the form of "x = ...".  

Since we know x value of the vertex is -4, we know the line of symmetry will be x = -4

step-by-step explanation:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
