First part
Thus the first part's blank should be filled in with 4x
Second part
Thus the second part's blank should be filled in with 2x + 10
Hope that helps!
Plug in x = -4 and then use PEMDAS to simplify
f(x) = 5(3-x)^2
f(x) = 5*(3-x)^2
f(-4) = 5*(3-(-4))^2 ... replace every x with -4
f(-4) = 5*(3+4)^2
f(-4) = 5*(7)^2
f(-4) = 5*(49)
f(-4) = 245

Final Answer: 245
