Answer:
T F T T.
Step-by-step explanation:
Let p and q be two statement
When the value of p is true and the value of q is true then the value of
is true.
When the value of p is true and the value of q is false then the value of
is true.
When the value p is false and the value of q is true then the value of
is false.
When the value of p is false and the value of q is false then the value of
is true.
Hence, the value of
is false when q is true and p is false.
To find f(-2), substitute (-2) into x of the function f(x) = 4x^2-2
We get, f(-2) = 4(-2)^2 - 2
= (4*4)-2 = 16-2 = 14
Therefore, f(-2)=14.
