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).

F(-5) just means that your substituting the number -5 for every x value. So if you have x+1 this would be -5+1 which is -4

The difference of 2 and the product of 3and k
allsm [11]
2-3k because the difference between something means it is subtraction and the product of 3 and k would just be 3k since you don't know what k is.

There are 8 flowers in a garden. Some insects (butterflies and dragonflies) sit on flowers. There is no more than one insect per
tester [92]

Answer:

4

Step-by-step explanation:

x butterflies and y dragonflies

4 < x + y 《 8

x = 2y

4 < 2y + y < 8

4 < 3y < 8

Only multiple of 2 between 4 and 8 is 6

So 3y = 6

y = 2

x = 2y = 4

Ten percent of the reds are added to twenty percent of the blues, and the total is 24. Yet the product of the number of reds and
salantis [7]
0.10r + 0.20b = 24
3r = b + 20....b = 3r - 20

0.10r + 0.20(3r - 20) = 24
0.10r + 0.60r - 4 = 24
0.70r = 24 + 4
0.70r = 28
r = 28/0.70
r = 40 <=== there are 40 reds

0.10r + 0.20b = 24
0.10(40) + 0.20b = 24
4 + 0.20b = 24
0.20b = 24 - 4
0.20b = 20
b = 20/0.20
b = 100 <=== there are 100 blues
