Answer:
= 4/75
Step-by-step explanation:
f(x) = x-3/2x+7
f(4) = 4-3/ 2(4) + 7
f(4)= 1/ 8+7
f(4)= 1/15
f(-1) = -1-3/ 2(-1) + 7
f(-1) = -4/ -2 + 7
f(-1) = -4 / 5
therefore,
f(4) × f(-1)
= 1/15 × -4/5
= -4/75
I hope this will help you

Answer:
f(x) =x-3/2
f(4)=4-3/2
=5/2
f(-1)=-1-3/2
=-5/2
f(4)Xf(-1)==5/2*-5/2
=-25/4
