Answer:
Step-by-step explanation:
Plug each value of x into the equation and solve for the corresponding y value.
When x = -1, y = (-1)²-2(-1) = 3
When x = 0, y = 0² - 2(0) = 0
You can finish from here.

Answer:
Step-by-step explanation:
This might be familiar to you if you know about the pythagorean relationship in right triangle, aka pythagoras's theorem.
It states that, in a right triangle, the sum of the squares of the 2 shorter sides equals the square of the longest side, aka the hypotenuse.
Note that the triangle in this case is a right angled triangle, and all the surrounding shapes are squares.
So by the pythagorean relationship we have,
2^2 + 4^2 = c^2
4 + 16 = c^2
20 = c^2
c = sq root 20 = 2 * sq root 5
Hope it helps and if it does, plzzz mark me brainliest ;-)
