Answer: х=3.
Step-by-step explanation:
А point is missing here: determining the allowable values of x for this equation.
1. Consider the right side of the equation:
The root expression 2x+3 must be greater than or equal to 0.
2x+3≥0
2x≥-3\ |:2
x≥-1,5.
2. Consider the left side of the equation:
the left side of the equation must be greater than or equal to 0.
x≥0.
We get x≥0. ⇒
х=3 ∈ х≥0
х=-1 ∉ х≥0.

Step-by-step explanation:
Solve the Function Operation
Given g (x) = −3x + 3 , find g (−2)
Replace the variable x with −2 in the expression.
g (−2) = −3 ⋅ −2 + 3
Simplify −3 ⋅ −2 + 3
Remove parentheses.
−3 ⋅ −2 + 3
Multiply −3 by −2.
6 + 3
Add 6 and 3.
