what is f(-3) if f(x)=[2x+1]+5
0
10
12
-10
F(-3)=10
To find the value of f(-3), we substitute -3 into the expression for f(x):
f(-3) = [2(-3) + 1] + 5
Now we can simplify:
f(-3) = [-6 + 1] + 5
= -5 + 5
= 0
Therefore, f(-3) is equal to 0.
To find the value of f(-3) for the given function f(x) = (2x + 1) + 5, you need to substitute -3 for x in the function and compute the result.
So, start by replacing x with -3 in the original function:
f(-3) = (2(-3) + 1) + 5
Now, simplify the expression:
f(-3) = (-6 + 1) + 5
f(-3) = -5 + 5
f(-3) = 0
Therefore, f(-3) equals 0.
