The vertex for f(x)=(x+1)^2-2 would represent a minimum because the coefficient of the binomial (x+1) squared term is positive (understood to be in front of the parenthesis). Think about the Vertex From: y=a(x-h)^2+k where "a" is the coefficient of the binomial and(h, k) is the vertex. If "a" is positive the parabola opens up U (Making the vertex the lowest point of the graph). If "a" is negative the parabola opens down N (making the vertex the highest point of the graph)

Therefore:

The vertex of f(x) is a minimum because a=1.

The vertex of g(x) is a maximum because a=-1.

These equations are already in vertex form. So, we can easily find the vertex of each equation.

f(x) = -(x-1)^2 - 2

Vertex: (1,-2)

The vertex in this equation is the maximum because it faces down (a=-1).

g(x) = (x+2)^2 + 1

Vertex: (-2,1)

The vertex in this equation is the minimum because it faces up (a=1).

Can y’all help please

Answer:

x=square root 63. Basically the radical 63.

Step-by-step explanation:

So in the first triangle with the 3 in it. You have root 3 and use the a^2 +b^2=c^2 formula. So 3^2 + 3^2= x^2 and then when you solve you get radical 18^2 which is equal to radical 18 or square root 18. Then we go to the bigger triangle and we do the same formula but this time we have the c value which is 9. So we do radical 18^2 + x^2 = 9^2 and then solve that and minus 18 from the 81 since the radical goes off the 18 and you get square root63.

Sorry i couldn't use the signs. Sorry If I'm wrong Hope this helps!.
