How do you find the vertex of an function in vertex form?

To find the vertex it the h and k.
For ex: 4(x+5) 7
Ur h is - 5 and ur k is 7
So the vertex is (-5,7)
Also u take the opposite what in the parenthesis, since it positive 5, it becames - 5.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
