To estimate the value for g(10), that means that you have to substitute 10 in every x of g(x), then $$g(x) =x^2-10$ exists g(10) = 90.

The value of g(10), we have to substitute in every x of f(x), the

$f(x) = 2x + 1$ exists f(90) = 181

Therefore, the value of f[g(10)] exists 181.

<h3>How to estimate the value of f[g(10)]?</h3>

To estimate the value for g(10), that means that you have to substitute 10 in every x of g(x), then

$$g(x) =x^2-10$

substitute the value of x = 10

$$g(10) = (10)^2-10$

simplifying the equation, we get

g(10) = 100 - 10

g(10) = 90

We have the value of g(10), we have to substitute in every x of f(x), then

f(x) = 2x + 1

substitute the value of x = 90

f(90) = 2(90) + 1

simplifying the equation, we get

f(90) = 180 + 1

f(90) = 181

The value of f[g(10)] exists 181.

Therefore, the correct answer is option b) 181.
