Question

@sadellite73 please help me on this

Answer 1

Compare the functions shown below:


f(x) = 2 sin (3x + π) − 2 g(x) = (x − 3)2 − 1
h(x)

x y
-2 3
-1 -2
0 -5
1 -6
2 -5
3 -2
4 3


Which function has the smallest minimum y-value?
f(x)
g(x)
h(x)
Both g(x) and h(x) have the same minimum y-value.

Answer 2

wrong one

Answer 3

Compare the functions shown below:


f(x) = 2 sin (3x + π) − 2 g(x) = (x − 3)2 − 1
h(x)

x y
-2 3
-1 -2
0 -5
1 -6
2 -5
3 -2
4 3


Which function has the smallest minimum y-value?
f(x)
g(x)
h(x)
Both g(x) and h(x) have the same minimum y-value.

Answer 4

@satellite73

Answer 5

for h(x) the smallest value of y is -6, right?

Answer 6

for g(x) the vertex of upward parabola is (3,-1), hence the smallest value of y is -1, right?

Answer 7

for f(x) , the sin function has the amplitude |2|, hence the smallest value of y is -2. However, the whole thing -2 at the end of the right hand side forces you down the whole graph 2 units. So, the smallest value of y of f(x) is -4
Now, you have 3 of them, compare and make conclusion by yourself.

Answer 8

i hate ur mom
