I should be on the black dot ☺️
There is a Y axis and a X axis on the graph, they can be our equation. If the plot is (1,3) then, X=1 and Y=3, you can assume that it's X = 3. If the plot is (2,4), then X = 2, Y = 4, just divide/ simplify both sides my 2, and X = 2.
The answer would be — m>/-3
——the arrow is pointing to all numbers larger than -3, including -3
yes but no because you would have to put a 6 at the end so it should look like this.406.84375
Step-by-step explanation:
The given function is :

(a) To find f(9), put x = 9 in the above expression.

(b) To find f(x+7), put x = x+7 in the above expression.

(c) To find f(-x), put x = -x in the above expression.

Hence, this is the required solution.
