Answer:
(2, - 9 )
Step-by-step explanation:
Since 2 is the output when - 9 is input to f(x)
Then reversing the procedure, that is the inverse gives an output of - 9 for an input of 2.
(- 9, 2) is a point on the graph of f(x), then
(2, - 9) is a point on the graph o the inverse function (x)
D. Although I'm not 100% sure
Answer:
B
Step-by-step explanation:
Since the triangle is right use the sine/ tangent ratios to solve for x and y
note sin60° = and tan60° =
sin60° = =
ysin60° = 3
y × = 3
multiply both sides by 2 and divide by
y v= 6 = 6
tan60° = =
xtan60° = 3
x × = 3
divide both sides by
x = 3 = 3
Answer: C) Cannot be done
Taking the square root of a negative number is not possible unless you involve complex numbers. If your teacher has not introduced that topic yet, then you just simply say "cannot be done" or something along those lines.
