Pls help Considering only functions that have a rate of change less than that represented in the graph, which function has the greatest rate of change?

y=2x+7 y=1.5x+1

y=0.5x-5 y=2.5x-20

y=3x+12 y=x+7

good after noon and thank you for helping me

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.

step-by-step explanation:

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
