Given: f(x)=(2x-2)/4
find f^-1(3)?
we need to find the inverse of f(x), so
x=(2y-2)/4
2y-2=4x
y-1=2x
y=2x+1
so, then f^-1(x)=2x+1
f^-1(3)=2(3)+1
=6+1
=7
so, the answer is 7
We are given with the expression arctan(-sqrt(3)) and asked to evaluate it. In this case, we can use a calculator or the rule of common triangles to answer this question. the value of <span>arctan(-sqrt(3)) is -60. Since negative tan is found in 2nd and 4th quadrant, the angles are 180-60 or 120 degrees and 360-60 or 300 degrees.</span>
Answer:
steps: divide, multiply, subtract, and bring down.
Step 1. Calculate how many times the number outside the division bar goes into the first number inside the bar. Step 2. Put the answer on top of the bar. Step 3. Multiply the number outside the division bar by the number at the top of the bar.
Answer:
Step-by-step explanation:
x=3 x=2. x=1
y=1 *3 y=1 *2. y=1 *1
y=1 y=1. y=1
(3,1). (2,1) (1,1)
‘The others are the same. Probably you can use a calculator too
Answer:
-11/20
Step-by-step explanation:
first you want to get a common denominator (number on the bottom)
now you can subtract the numerators (number on tope) (also don't touch bottom)
