If you divide 15 by 12 (the difference between the prices) then that's what you get :)
We can re-write the equation √(1-x) - 2y = 2 → - 2y = 2 - √(1-x)
→ 2y = - 2 + √(1-x) → and y = [ - 2 + √(1+x)]/2
Tis function "exists" as long as the radical is > or = to zero:
1+x > or = 0 → x>-1
{x ∈ R for x> =0}
Answer:
Step three incorrectly factors
Step-by-step explanation:
Answer:
f(3)=56, f(-4)=277
Step-by-step explanation:
f(x)=x^4-8x-11
f(3)=3^4-8(3)-11=3*3*3*3-24-11=9*3*3-35=27*3-25=81-25=56
f(-4)=(-4)^4-8(-4)-11=(-4)(-4)(-4)(-4)+32-11=(16)(16)+32-11=256+32-11=288-11=277
