PLEASE HELP ASAP I NEED DONE BEFORE 9 Function Notation 9.16)
Use f(x) = 5x – 20, g(x)=x2 + 5x - 11, and h(x) = (2x+7||
10. g(-3)

-14 is the answer

hope this : ))

step-by-step explanation:

my butt

the answer will be the last one

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
