Final answer:
To find the coordinates when f(x) = -20 for the function f(x) = -½x - 6, you solve for x in the equation, which gives you the point (28, -20).
Step-by-step explanation:
The question seems to be asking for the coordinates of a function f(x) where the function's value is given by the equation f(x) = -½x - 6 and we are to find the x value when f(x) = -20. To find x, we would set f(x) = -½x - 6 equal to -20 and solve for x:
- -½x - 6 = -20
- -½x = -20 + 6
- -½x = -14
- x = -14 ÷ (-½)
- x = 28
So the coordinates when f(x) = -20 are (28, -20).
