Question

F(25)+g(-2) если f(x)=корень x,a g(x)=x3

Answer 1

$f(x)=\sqrt{x} \Rightarrow f(25)=\sqrt{25}=5\\\\g(x)=x^{3}\Rightarrow g(-2)=(-2)^{3}=-8\\\\f(25)+g(-2)=5+(-8)=5-8=-3$

Answer 2

To evaluate the expression F(25) + g(-2) using the given functions f(x) = √x and g(x) = x^3, we need to substitute the respective values and calculate the results.

Let's start by evaluating F(25):

f(x) = √x

Substituting x = 25:

f(25) = √25 = 5

Now, let's evaluate g(-2):

g(x) = x^3

Substituting x = -2:

g(-2) = (-2)^3 = -8

Finally, we can calculate the expression:

F(25) + g(-2) = 5 + (-8) = -3

Therefore, F(25) + g(-2) equals -3.
