Solve for x: −3|x + 7| = −12

Answers

Answer 1
Answer: -3Ix + 7I = -12              (divide -3 from each side)

Ix + 7I = -12/3

Ix + 7I = -4

x + 7 = -4     or      -x - 7 = -4

 x = -11          or       -x = 3  
                                  x = - 3


x = -3 or -11
Answer 2
Answer: -3|x+7|= -12
⇒ |x+7|= -12/(-3)
⇒ |x+7|= 4
⇒ x+7= 4 or x+7= -4
⇒ x= 4-7 or x= -4 -7
⇒ x= -3 or x= -11

Final answer: x= -3 or x= -11~

The range of which function is (2,infinity)?y = 2x?
y = 2(5x)?
y = 5x +2?
y = 5x + 2?

Answers

For a function: y = 5^x
range is ( 0 , + ∞ )
And we have: y = 5^x + 2 , which is translated 2 units up.
So the range is ( 2, + ∞ ) or ( 2, infinity ).
Answer:
D ) y = 5^x + 2

The exponential function that has range of (2, infinity) is given by:

y = 5^x + 2

What is an exponential function?

It is modeled by:

y = ab^x + c

In which:

  • a is the initial value.
  • b is the rate of change.
  • The range is (c, infinity).

Hence, the exponential function that has range of (2, infinity) is given by:

y = 5^x + 2
