Answer:
3.
Step-by-step explanation:
number 1 equals 8 1/5
number 2 equals 5
number 3 equals 9 1/3
The graph when translated 5 units up is g(x) = 3x + 5.
Consider a parent function f(x),
When translating a function up or down by a value (say b), you let g(x) = f(x) + b
If b is positive your graph is translated up, if b is negative your graph is translated down.
When translating a function to the right or left by a value (say a) you let g(x) = f( x + a).
If a is positive your graph is translated to the left, if a is negative your graph is translated to the right.
Therefore, the function g(x) when the graph of the function f(c) = 3x is translated 5 units upwards will be:
g(x) = f(x) + 5
g(x) = 3x + 5
The function g(x) when the graph of f(x) is translated 5 units up is g(x) = 3x + 5.

Answer:
-7
Step-by-step explanation:
y=2x+3
f(x)=2x+3
f(-5)=2(-5)+3=-10+3=-7
Im still trying to figure that answer out.. its hard
