Question 962539: This is confusing. My teacher may have written the question wrong, but I want to make sure. If it is written correctly, I don't know how to do this.
The function f is defined by f(x)=x^2-2x-24. If f(x+3)=x^2+kx-21, what is the value of k? Answer by josgarithmetic(39617) (Show Source):
You can put this solution on YOUR website! Use the definition to find the result of x+3 as input of the function. Examine the format of the general form expressions to determine k.
Definition:
Input (x+3):
You were given that .
You can simply equate the two formulas for f(x+3).
