Answer:

This function would be even.

Step-by-step explanation:

You can tell a function is even if you plug in -x for x and then simplify and it is the same function. This is the case below.

y = 2x^4 + 2x^2 ----> Plug in -x

y = 2(-x)^4 + 2(-x)^2 ----> Simplify

y = 2x^4 + 2x^2

You'll notice the simplified version is exactly the same as the original, which makes it odd.

Trava [24]

Answer:

(-5, -3)

Step-by-step explanation:

To graph the two equations, you can look at two things, the slope and the y-intercept.

The two equations are in slope-intercept form, y= mx + b. m is the slope and b is the y-intercept. The slope is rise/run and the y-intercept is where the line crosses the y-axis.

In the first equation, the slope is -1 and the y-intercept is -8. So, to graph you would start at (0, 8) and move up one unit and then left one unit to get the next point.

For the second equation, the slope is 2/5 and the y-intercept is -1. So, to graph you would do the same thing. Start at (0, -1) and then go up 2 units and right 5 units to get the next point.

I've attached a graph below if you need it.

Perfume is sold in two different sizes of bottle. The 80ml bottle is priced at £55. The 50ml bottle is usually priced at £45, bu
Nadya [2.5K]
1ml of 80ml bottle: 55/80 = 0.6875 pence

1ml of 50ml bottle: 45/50 = 0.9 pence

If no special offer the first bottle is a better value for money.

Since special offer though, you'd be buying;

50ml bottle £45 + another 50ml £22.5 = £67.5 in

which case 1ml would cost;

67.5/100 = 0.675 pence. Hence buying 2x50ml

bottle would be a better value.
