It's essentially asking for the value of y on the graph of function f(x) when x is equal to -4.
Graphically, we can see that when x = -4, y would be 1.
If you had to do this algebraically with an equation for the function, just slot the value of -4 in for x, to find the value for y.
Answer:
x=32
Step-by-step explanation:
Since all angles in a triangle add up to 180, set 2x+x+2x+20=180. Then solve for x, and you'll get 32. Hope this helped!
