okay i have to find f(a-2) out of this question
f(x)=5x-1
were did the a come from. man i am so confused?
"a" is a variable. Like "x" is in most equations.
So
5(a-2) - 1
Multiply it out from there and simplify.

In the given question, the function is defined as f(x) = 5x - 1. However, instead of substituting a value for x, you are asked to find f(a-2).
The variable "a" is introduced here as a placeholder, similar to "x" in most equations. It represents any arbitrary number or expression.
To find f(a-2), we need to substitute a-2 into the function in place of x.
So, let's substitute (a-2) into the given function equation:
f(a-2) = 5(a-2) - 1
Now, simplify the expression by distributing 5 to both terms inside the parentheses:
f(a-2) = 5a - 10 - 1
Combining like terms:
f(a-2) = 5a - 11
Therefore, f(a-2) equals 5a - 11.
Keep in mind that "a" can represent anything, such as a specific number or a different expression. The calculation shown above will be valid for any given value of "a".
