given the function k described by k(x)=x+20 find each of the following
k(0)=
k(-12)=
k(-9)=
k(15)=
k(y+1)=
Substitute that value for x in each case. For example:
k(10) = 10 + 20 = 30
To find the value of each expression using the function k(x) = x + 20, you simply substitute the given value into the function and perform the computation. Here's how you can find each of the following:
1. k(0):
Substitute x = 0 into the function: k(0) = 0 + 20
Perform the operation: k(0) = 20
The value of k(0) is 20.
2. k(-12):
Substitute x = -12 into the function: k(-12) = -12 + 20
Perform the operation: k(-12) = 8
The value of k(-12) is 8.
3. k(-9):
Substitute x = -9 into the function: k(-9) = -9 + 20
Perform the operation: k(-9) = 11
The value of k(-9) is 11.
4. k(15):
Substitute x = 15 into the function: k(15) = 15 + 20
Perform the operation: k(15) = 35
The value of k(15) is 35.
5. k(y + 1):
To evaluate k(y + 1), substitute x = y + 1 into the function: k(y + 1) = (y + 1) + 20
Simplify the expression: k(y + 1) = y + 21
The value of k(y + 1) is y + 21.
Note: For the last question, k(y + 1), the expression could not be simplified further since y is a variable, not a known value.
