Answer:
This is a function, because for every x-value, there is exactly one y-value.
The domain is: {-5, -4, -3, -2}, and the range is {-2, -1, 0}
Let me know if this helps!
Answer:
The distance formula is
The midpoint formula is
Step-by-step explanation:
apply the pythagorean theorem on a coordinate grid
Answer:
0.25x-3 would be the answer.
Step-by-step explanation:
y = mx+b
g(x) should intersect with the y-Axis where f(x) intersects with the x-Axis so both at negative 3 making b=-3
y=mx-3
Figuring out m I can't really explain to you, but when you divide 1 by whatever f has (in this case 4) you will get the new incline needed for g
y=(1/4)*x-3
We can also think of this problem as f(x) + g(x). Therefore, all we need to do is add the two functions together.
x + 4 + 3x^2 - 8 || Write it out!
3x^2 + x + 4 - 8 || Rearrange in order of decreasing exponents. No need to combine and rearrange all at once!
3x^2 + x - 4 || Combine like terms!
Hope this helps!! :)
What does that 3/x and 2/x mean? 2x and 3x or x^2 and x^3?
