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.
Rule: lines that are parallel have equal gradients.
Therefore y=-4/3x + b.
To find b, you must sub the point (6,2) into the equation y=-4/3x + b.
2= -4/3 x 6 + b
b=-10 (using algebra to solve)
Therefore y=-4/3x - 10.
For an increase of 15% you would add the increase percentage to 1 and multiply that by number of years.
So the multiplication rate would be 1.15
The answers are cut off in the picture, but the one with 1.15 is the top left answer.
Answer:
y= -3+7x
Step-by-step explanation:
7x-y=3 for y
Move variable to the right
-y+3-7x
Change the signs
y= -3+7x
