Answer:
g(2y) = 8y^2 -3
Step-by-step explanation:
g(x)=2 x^2 -3
Let x=2y
g(2y) = 2 (2y)^2 -3
= 2 (4y^2) -3
= 8y^2 -3
The tan(-x) is the same thing as -tan(x). The tangent function is also the same thing as sin(x)/cos(x), right? So let's rewrite that tan in terms of sin and cos:
is the same as
We can now cancel out the cos(x), which leaves us only with -sin(x) remaining. So your answer is A.
IT IS Biodarmate physical access process in great Aphrodite in which is will be used when both the variable size will be multiplied with both
Step-by-step explanation:
8x + x² - 2y + y² - 64 = 0
(x + 4)² + (y - 1)² - 81 = 0
(x + 4)² + (y - 1)² = 81
