Restrict the domain of the following parabolas so that their inverses will also be functions. Use the correct inverse notation to write down the
equations of the inverse functions. Sketch the graph of each parabola for
both restricted domains and the graph of the matching inverses on two
separate sets of axes.
b g(x) = x
h(x) = -5x²
d 2k(x) = -2
a F(x) = 5x

Ineed to know the answer to this algebra question.

Select the correct answer. what is the exact value of sin (157.5°)? a. 'sqrt(2 - sqrt(2))/2 b. *"-"'sqrt(2 + sqrt(2))/29 c.'sqrt(2 + sqrt(2))/4" d. "-"sqrt(2 + sqrt(2))/4)

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
