Plz help me find the answers to these questions

Step-by-step explanation:

range is in the y direction so

#6 is F because the y values are between -9 and 9 (the symbol shows less/greater than and equal to because -9 and 9 are y values)

#7 is A; because the graph has closed circles, the numbers y is equal to -4 and 5 so the symbols have to be less/greater than and equal to

6. J. {-9, -3, 3, 9}

7. A. - 4 ≤ x ≤ 5

Step-by-step explanation:

6.

The range is the set of numbers in the table

Correct choice is J.

7.

The range as per graph is the interval from -4 to 5 both inclusive

Correct choice is A.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
