Answer:
D. 3y + 1
Step-by-step explanation:
Answer:
Opt. 1 -3 ≤ x ≤ 3
Step-by-step explanation:
Inequalities are regions, the attached picture shows us a region located between -3 and 3, the dots used are solid, this means that the value '3' is include in the region.
Hence the variable is narrowed to -3 and 3.
The first step to solving this equation is to change the signs on both sides of the equation
y = -

x + 3
Since we don't know what x is but we do know why y is,, we will write our answer with the answer to y and x being left as undefined.
y = -

x + 3, x ∈ R

ANSWER

EXPLANATION
The parent square root function is

The translation

Will shift the graph of f(x) k units to left.
The translation

will shift the graph of f(x) to the right by k units.
Therefore if f(x) is shifted 4 units to the left its new equation is:
