2. vertical line
3. a vertex is a point of where the first derivative of curvature is zero.
4. the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.
Step-by-step explanation:
translation.........
b=12
a^2+b^2=c^2
(9×9) + b^2= 15×15
81+ b^2= 225
-81. -81
b^2=144
√. √
b= 12
f(10) = 13
f(x) = x/2 + 8
Let x = 10
f(10) = 10/2 +8
f(10) = 5+8
it goes down by 4 every number
