x=-3 then y= 27
x= -2 then y= 9
x=2 then y:
x=3 then y:
The graph of the function decreases from left to right.
Option C is correct.
Step-by-step explanation:
We are given the function:
and we need to fill the table
if x = -3 then y=?
Putting value of x in the given function:
Applying exponent rule a^-b= 1/a^b
if x = -2 then y=?
Putting value of x in the given function:
Applying exponent rule a^-b= 1/a^b
if x = 2 then y=?
Putting value of x in the given function:
Applying exponent rule a^-b= 1/a^b
if x = 3 then y=?
Putting value of x in the given function:
Applying exponent rule a^-b= 1/a^b
So, x=-3 then y= 27
x= -2 then y= 9
x=2 then y:
x=3 then y:
Graph of the function is shown in figure attached.
The graph of the function decreases from left to right.
Option C is correct.

Answer:
see explanation
Step-by-step explanation:
(a)
The angle around the centre O of the circle = 360°, then
∠ AOB = 360° - 260° = 100°
Δ AOB is isosceles ( the radii OA and OB are congruent )
The altitude from O bisects ∠ AOB , thus
y = 50°
Since the triangle is isosceles the 2 base angles are congruent, so
x = =
= 40°
(b)
∠ POR = 360° - 254° = 106°
Δ POR is isosceles (the radii OP and OR are congruent ) , then
the 2 base angles are congruent , thus
a = =
= 37°
