Let's see.
We have function . We have to determine if the function is even or odd or neither.
We can find this out in many ways but the assignment specifically asks to prove this algebraically.
Function is even if , so,
Which is true since negative raised to an even power is positive to that same number.
Similarly, function is odd if , that is,
.
So we have prooved that function is an even function not an odd function and therefore also not neither.
Hope this helps.
Answer:
Step-by-step explanation:
Find the multiples of 2x^2 and 2
for 2x^ you get 2,1 but they need to have x to get x^2 so; (2x and x)=2x^2
for 2 you get 2,1 (2x1)=2
Because your equation has a 5x and no negatives you know that your factors need to be positive.
(2x+1)(x+2)
when you multiply these you get
2x^2+4x+x+2 (remember 2x multiplies with everything inside (x+2) = 2x^2+4) and so on for the x (x+2) =x+2 )
Then you combine like terms 4x+x=5x
and those are the only like terms available and you get
2x^2+5x+2

Answer:
Step-by-step explanation:
Given
Number of Toys = 50
Unit Cost Price = $5.5
Unit Selling price = $15
Required
Determine the profit after sales
First, we need to determine the total cost price;
First, we need to determine the total sales;
____________________________________________________
Half of the toy was sold at $15;
____________________________________________________
Two-fifth of the remaining was sold at half of the sales price
From the above calculation;
<em></em>
<em>Calculating Two-fifth of the remaining:</em>
<em>Calculating half of the sales price:</em>
This means that 10 toys were sold for $7.5
____________________________________________________
The remaining was sold at one-third of the sales price
From the above calculations (1 & 2);
<em>Calculating </em>one-third <em>of the sales price:</em>
This means that 15 toys were sold for $5
____________________________________________________
Now the total sales can be calculated;
