Answer:
1) for -1 as x, k(x) would be -8
2) for -3 as x, k(x) would be -18
3) for 0 as x, k(x) would be -3
4) for 1 as x, k(x) would be 2
the answer is:
j= 76
k= 65
We are finding hypotenuse:
6^2 + 8^2
36 + 64 = 100
Now we need to find a number that should be squared to equal 100.
10^2 = 100!
10 is your answer.
