Hello students here in this question: according to graph, we see that the domain for function is minus 2 to infinity. Therefore, let required function that is b y is equals to a into log base b of x, plus 2 plus b. Now take it as equation 1. Now we see that graph passes 2 point minus 1 and 3 point. Therefore putting in a bepissequation will get 3 is equal to a into log base b. Minus 1 plus 2 plus 3 implies will get. The value of c is equal to 3, as log base of 1 is equal to 0, which implies first equation will become, as is equal to a into log base b of x, plus 2 plus 3 is take it as equation. 2 also graph passes through .0 comma 4. The 4 putting above will get 4, is equal to a into log of base b, 0 plus 2 plus 3, which implies we’ll get the value of a log b of 2 is equals to 1. Take it as equation 3 now graph passes through .2 comma 5. Therefore, from second equation will get is equal to a into log of of 2 plus 2 plus 3, which implies we’ll get a log base b of 2 is equal to 1, which is same as third equation. Now, as we have given base of log is an…
