X+1)=3 Which of the following correctly soles for x?
A
X = 4
3
x=
B
x=31
Oct-2
D
x = 2

A) x = 4¾

Step-by-step explanation:

x + 5/4 + 14/4 = 19/4 = 4¾

A

Step-by-step explanation:

Choice A is correct. Since f(x) =

_3

2

x + b and f(6) = 7, substituting 6 for x in

f(x) =

_3

2

x + b gives f(6) =

_3

2

(6) + b = 7. Then, solving the equation

_3

2

(6) + b = 7

for b gives

_18

2

+ b = 7, or 9 + b = 7. Thus, b = 7 − 9 = −2. Substituting this

value back into the original function gives f(x) =

_3

2

x − 2; therefore, one can

evaluate f( −2) by substituting −2 for x: _3

2

(−2) − 2 = −_6

2

− 2 = −3 − 2 = −5.

Choice B is incorrect as it is the value of b, not of f(−2). Choice C is incorrect

as it is the value of f(2), not of f(−2). Choice D is incorrect as it is the value of

f(6), not of f(−2).

b
