Answer:
2x² + 6
Step-by-step explanation:
f(g(x)) = 2(g(x))
= 2(x² + 3)
= 2x² + 6
Answer:
the 3rd one is the graph answer
Answer:
(x + 1)² + (y + 5)² = 48
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 1, - 5) and r = 4
, so
(x - (- 1))² + (y - (- 5))² = (4
)², that is
(x + 1)² + (y + 5)² = 48 ← equation of circle
The answer is 74.90.
