So k in the first problem would =1/2
and i guess in the second problem just put k in place of the first space and in the second space put 8 for x. y would then =4. Idk if I did this right, though, I'm honestly a little confused too.
F(13) means x equals 13.
Replace x in the equation with 13 and solve:
-13 + 3 = -10
F(13) = -10
What do you mean by without calculating?
Answer:
x^2+12x+36=1+36
Step-by-step explanation:
you divide the 12 by 2 which is 6 and then square it (36)
