Answer:
A: Function <em>f</em>.
Step-by-step explanation:
Let's find the maximum <em>y-</em>value of each function.
Function <em>f </em>is given by:

Remember that the value of cosine is always between -1 and 1. In other words:

Then assuming the greatest value for cosine, we can substitute it for one:

Function <em>g</em> is given by the graph.
Looking at the graph, we can see that the maximum <em>y-</em>value of <em>g</em> is 3.
Finally, function <em>h</em> is given by the table.
Looking at the table, the maximum <em>y-</em>value of <em>h</em> is -2.
Therefore, function <em>f</em> has the greatest maximum <em>y-</em>value.
Answer:
-6
Step-by-step explanation:
This is similar to collecting like terms in Algebra, that is
- 2x - 7x + 3x = x(- 2 - 7 + 3) = - 6x
Similarly
-2
- 7
+ 3
=
(- 2 - 7 + 3) = - 6
Answer:
2x-3=y
Step-by-step explanation:
let age of sister be x
my age be y
therefore 2x-3=y
That would be 8x, Aubreglorgaby.
x - 1 + 4 + 7x -3
8x - 1 + 4 - 3
8x + 3 - 3
8x + 0
8x
