Answer:
f(-2) = 2 and f(0) = 0.
Step-by-step explanation:
The piece wise function is given by, f(x) = x³ for x ≠ - 2 and f(x) = |x| for x = - 2.
Now, as defined above at x = -2, f(x) = |- 2| = 2
So, f(-2) = 2
Again, at x = 0, f(x) = x³ = (0)³ = 0.
So, f(0) = 0.
Hence, f(-2) = 2 and f(0) = 0. (Answer)
Answer:
Mr.Kim is presently 40 years old, and his daughter is 15 years old.
Step-by-step explanation:
K is Mr Kim's present age
D=his daughter's present age.
K=D+25 ; or Mr.Kim is his daughter's age plus 25 years.
K+10=2(D+10); or in 10 years, Mr Kim will be twice daughters age
Substitute the K from the first equation into the second equation and then solve for variable D.
(D+25)+10 = 2(D+10) Simplify.
D+35 = 2D+20 You must subtract D from both sides.
35 = D+20 Lastly, subtract 20 from both sides.
15 = D or D = 15
Mr Kim's daughter's is 15 years old.
Mr Kim's age is D+25
15+25 = 40 years old.
