Find the range of the function f(x) = 4x – 1 for the domain {-1, 0, 1, 2, 3}. A. {-5, -3, 0, 7, 11}
B. {-5, -4, -3, -2, -1}
C. {-11, -7, -3, 1,5}
D. {-5,-1, 3, 7, 11}

D

Step-by-step explanation:

f(-1) = -5, so C is incorrect

f(0) = -1, so D is correct

$20.01

step-by-step explanation:

the sale price is (1.00 - 0.77)($87), or 0.23($87), or $20.01.

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
