If f(x) = x + 1 and g(x) = 2x - 7, which expression is equivalent to [fog|(3)?

Answer and Step-by-step explanation:

First, we plug in the value of 3 for x in g(x), then we plug the answer os g(x) into the value of x in f(x).

g(3) = 2(3) - 7

Multiply 2 by 3, then subtract 7.

g(3) = 6 - 7

g(3) = -1

Now, we plug -1 for x in f(x).

f(g(3)) = f(-1) = -1 + 1

f(-1) = 0

The value of f(g(3)) is 0.

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a
