When you find f(2) for a given function f, you are finding the y value associated with x= 2
sveticcg [70]

Answer:

The provided statement is TRUE.

Step-by-step explanation:

The function <em>f</em> is an expression in variable <em>x</em>.

The entire expression can either be denoted by f (x) or <em>y</em>.

For instance consider the quadratic expression:

f (x) = ax² + bx + c

≡ y = ax² + bx + c

So, on computing the value of f (2), it implies that we are computing the value of y for <em>x</em> = 2.

Thus, the provided statement is TRUE.
