In Exercise, sketch the graph of the function.<br> f(x) = 0.5 ln x

BartSMP [9]

Answer:

To $f(x)=0.5ln(x)}$

view graph

Step-by-step explanation:

To $f(x)=0.5ln(x)}$ we can say that $f(x)=y=0.5ln(x)}$ then we find cut points. For y=0 $0=0.5ln(x)$ ⇒ $0=lnx\\e^{0}=e^{lnx}\\1=x$

as can be seen in the graph for any value of y greater that 0, x will always take values greater than 1, for values of y less than 0, x will take values less than 1

-15X - 40 = 23 - 8<br> This is the problem and I am totally lost

Elena-2011 [213]

-15x-40=15
then add 40 to both sides to get the constants on 1 side and variables on the other
-15x=25
now you just divide by -15
x = -1.67 or x = -1/3
