Given the graph of y = 2x² is transformed into y = -2x² + 3.  

For any function y = f(x), the transformation y' = -y = -f(x) reflects the graph across x-axis.

So it means that y = -2x² is the reflection of y = 2x² across the x-axis.

For any graph y = g(x), the transformation y' = y + k = g(x) + k shifts the graph 'k' units upward for all value of 'k' > 0.

So it means that y = -2x² + 3 is the shifted version of y = -2x² by '"3 units up".

Hence, option B and C are correct i.e. "reflection across x-axis" and "shift of 3 units up".

Circle theorems please help
suter [353]

Answer:

n = 28°

Step-by-step explanation:

The angle at the centre is twice the angle on the circle subtended on the same arc.

Also angles subtended on the same arc are congruent , thus

m = n

Then

35 + m = \frac{1}{2} (98 + n ) ← multiply both sides by 2 to clear the fraction

70 + 2m = 98 + n , but since m = n, then

70 + 2m = 98 + m ( subtract m from both sides )

70 + m = 98 ( subtract 70 from both sides )

m = 14 and n = 28
