Using the function f(X)=-3X+1 find f(2M+5)

the (2M+5) takes the place of X in the function

f(2M+5) = -3(2M+5) + 1

To find f(2M+5) using the function f(X) = -3X+1, we need to substitute the value of (2M+5) into the function and simplify.

Step 1: Replace X in the function with the given expression (2M+5):
f(2M+5) = -3(2M+5)+1

Step 2: Distribute the -3 across the parentheses:
f(2M+5) = -6M - 15 + 1

Step 3: Simplify the expression by combining like terms:
f(2M+5) = -6M - 14

So, the value of f(2M+5) using the function f(X) = -3X+1 is -6M - 14.
