6 0

The answer is: "72" .
______________________________________________
(input value, or "x") / 10 = y = f(x);

When y = 7.2, what is the value of "x" ?

x / 10 = 7.2 ;

x = (7.2) * 10 = 72 .

The function f is defined by f(x)=2.1x−1.7. Use this formula to find the following values of f. f(x+2)

Yuki888 [10]

The value of $f(x+2)=2.1x+2.5$

Step-by-step explanation:

Given: The function $f(x)=2.1x-1.7$

Using this formula, we need to find the value of $f(x+2)$

Hence, we need to substitute $x$ by $x+2$ to find the value of $f(x+2)$

$f(x+2)=2.1(x+2)-1.7$

Multiplying the term $(x+2)$ by $2.1$ , we get,

$f(x+2)=2.1x+4.2-1.7$

Adding the constant term,

$f(x+2)=2.1x+2.5$

Thus, the value of $f(x+2)$ is $f(x+2)=2.1x+2.5$
