Describe the transformation of y = f(x) for the new function y = -f(x)

A. The graph of y = f(x) was flipped horizontally across the y axis.

B. The graph of y =f(x) was shifted up

C. The graph of y = f(x) was flipped vertically across the x axis.

D. The graph of y = f(x) was shifted down

Guys i really need or i have to stay late up night

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. 4x^2 + 20x + 25 = 0

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
