Answer:

Value is 7

Step-by-step explanation:

We are given the expression, $\frac{7}{8}\times c$ .

It is required to evaluate the expression for c= 8.

So, after substituting the value of c= 8 in the given expression, we get,

$\frac{7}{8}\times c$ = $\frac{7}{8}\times 8$ = 7

Hence, the value of the expression at c= 8 is 7.

Answer:
7

Explanation:
We are given the equation:
 $\frac{7}{8}$ * c

We want to get the value of the equation at c = 8.
Therefore, all we have to do is substitute c in the equation with 8 and solve as follows:
 $\frac{7}{8}$ * 8

= $\frac{7*8}{8}$

The 8 in the numerator will be cancelled out with the 8 in the denominator leaving us with only the 7 as a solution

Hope this helps :)

Answer:

$\boxed{f(6) = 34}$

Step-by-step explanation:

Composition of functions occurs when we have two functions normally written similar or exactly like f(x) & g(x) - you can have any coefficients to the (x), but the most commonly seen are f(x) and g(x). They are written as either f(g(x)) or (f o g)(x). Because our composition is written as $(f \circ g)(2)$ , we are replacing the x values in the g(x) function with 2 and simplifying the expression.

$g(2) = 3(2)$

$g(2) = 6$

Now, because we are composing the functions, this value we have solved for now replaces the x-values in the f(x) function. So, f(x) becomes f(6), and we use the same manner as above to simplify.

$f(6) = (6)^2-2$
