Identify function and input: Identify the function and the input value.We are given the function k(x)=6x+100 and we need to find the value of k(−5).
Substitute input into function: Substitute the input value into the function.To find k(−5), we substitute −5 for x in the function k(x)=6x+100.So, k(−5)=6⋅(−5)+100.
Perform calculation: Perform the calculation.Now we calculate the value of k(−5):k(−5)=6×(−5)+100k(−5)=−30+100k(−5)=70
