We are given that a function
We have to find three statements which describes function accurately.
Substitute x=0
We know that exponential is defined for all real numbers .
Given function is exponential function.
Therefore,
Domain=R
Range of f=y>0
Initial value means when x=0
Therefore, the initial value=3
The simplified base=
Answer:
Step-by-step explanation:
( g ° f )(x) = ( x + 7 )² = x² + 14x + 49
20 + 3(x² + 14x + 49) = - 34
20 + 3x² + 42x + 147 = - 34
3x² + 42x + 201 = 0 ⇔ x² + 14x + 67 = 0
D = 196 - 268 = - 72 < 0
There is no any roots in set of real numbers.
The values of x in set of complex numbers are:
