Answer:
f=√-25x-y/40or or f=-√-25x-y/40or
Step-by-step explanation:
Let's solve for f.
y=−25x+10forf(−4)
Step 1: Flip the equation.
−40f2or−25x=y
Step 2: Add 25x to both sides.
−40f2or−25x+25x=y+25x
−40f2or=25x+y
Step 3: Divide both sides by -40or.
-40f^2or/-40or = 25x+y/-40or
f^2=-25x-y/40or
f=√-25x-y/40or or f=-√-25x-y/40or
Hope it helped!
