This question is not elaborate.
7 = 3 does not make sense.
Otherwise, do you mean x = 3?
Please revise your question.
Answer:
6
Step-by-step explanation:
Half of eight = four
3/4
Double three = six
F(x)=3x^2-5 when x=-11
f(-11)=3(-11)^2-5
f(-11)=-33^2-5
f(-11)=1089-5
f(-11)= 1084
Hope this could help!
