Hello I have a calculus test to do and it's timed and it can only be open 1 time can you do that

60374 assignment
1) .
2)
−a) (-4-x-a)
a to get –x-a-4
3) Graph B is correct. Because for x >0 we have line is having negative slope so it would slant from left to right. Also f(0) is not included in that so a circle is rounded on (0,3). For x<=0, the line has positive slope and also f(0) is defined.
4)Take log. We get 5x-2 log 7 = log 42.
    log 42
    1.623249
    log 7
    0.845098
     
     
    5x-2
    1.920782
    x
    0.784156
