Given the function f(x)=x^2+5x+5 , to get the zeros we solve using quadratic formula;
x=[-b(+or-) sqrt(b^2-4ac)]/(2a)
from our function;
a=1,b=5, c=5
thus,
x=[-5(+or-)sqrt(5^2-4*1*5)]/(2*1)
x=[-5(+or-)sqrt(25-20)]/2
x=[-5+/-sqrt(5)/2
The answer is option C
Answer:
Option (2)
Step-by-step explanation:
Given functions are,
c(x) = 
d(x) = x + 3
Equation of the composite function will be,
(cd)(x) = c(x) × d(x)
= 
= 
This function is defined only when denominator is not equal to zero.
(x - 2) ≠ 2
Therefore, for real numbers except x = 2 will be the domain of the composite function.
Option (2) will be the answer.

Answer:
23
Step-by-step explanation:
We are given that
f(2)=13


We have to find the possible small value of f(7).
We know that

Using the formula


We have






The small value of f(7) can be 23.
Interchange the x and y and solve for the resulting y.
x = 4y^2 - 2
(x + 2) = 4y^2
(x + 2)/4 = y^2
+/- sqrt(x + 2)/2 = y
The graph of these two is below.

The inverse is in blue and green
