evaluate
f(3) when f(x)=5x=9
please help me. i don't understand what the f stands for and what im supposto do...
thanks!
To evaluate the given expression f(3) when f(x) = 5x + 9, we need to substitute the value of 3 in place of x in the expression f(x).
The function f(x) represents a mathematical relationship, where any input x will result in a corresponding output f(x). In this case, the function f(x) is defined as 5x + 9.
To evaluate f(3), we will substitute 3 in place of x in the expression f(x) = 5x + 9:
f(3) = 5(3) + 9
= 15 + 9
= 24
Therefore, f(3) equals 24.
