if P(2)=32 then that is ur answer
if P(2)=32 then that is ur answer
Answer:
Option B - [tex]g(x) = 4(x+3)^2-68[/tex]
Step-by-step explanation:
Given : Function is x = 2 mapped to 32.
To find : Which function is it ?
Solution : We put x=2 in every function and which result to 32 is the answer.
A. [tex]f(x) = -3x^2-4[/tex]
[tex]f(2) = -3(2)^2-4[/tex]
[tex]f(2) = -3(4)-4[/tex]
[tex]f(2) = -12-4[/tex]
[tex]f(2) = -16[/tex]
B. [tex]g(x) = 4(x+3)^2-68[/tex]
[tex]g(2) = 4(2+3)^2-68[/tex]
[tex]g(2) = 4(5)^2-68[/tex]
[tex]g(2) = 4(25)-68[/tex]
[tex]g(2) = 100-68[/tex]
[tex]g(2) = 32[/tex]
C. [tex]h(x) = 3x[/tex]
[tex]h(2) = 3(2)[/tex]
[tex]h(2) = 6[/tex]
D. [tex]j(x) = 2x-62[/tex]
[tex]j(2) = 2(2)-62[/tex]
[tex]j(2) = 4-62[/tex]
[tex]j(2) =-58[/tex]
Option B -[tex]g(x) = 4(x+3)^2-68[/tex] gave you the result [tex]g(2) = 32[/tex]
Therefore, Option B is correct.
