Answer:
5
Step-by-step explanation:
f(-4) = sqrt(2(4)^2 -7) (Plug in -4)
f(-4)= sqrt(2(16)-7) (Square 4 which is 16)
f(-4)=sqrt(32-7) (Multiply by 2)
f(-4)=sqrt(25) (Subtract 7)
f(-4)=+/- 5 (take the square root of 25 which is postive/negative 5)
Since this is a function there can only be one y to an x the positive 5 is the only answer
