Question

Which equation is represented by the graph below?

Answer 1

Answer:

the graph represente the log graph.

Answer 2

The graph represents C) y = ln(x) + 4  equation.

• The equation can't be A or B, because they are exponential functions, and they can have negative x-values.
• It must be one of the two ln functions because they can't have negative values of x.
• To decide between C and D, insert a value of x that makes it easy to calculate the value of y.
• Let x = 1.

       For Equation C,

       y = ln(1) + 4  = 0 + 4 = 4

• For Equation D,

        y = ln(1) + 5  = 0 + 5 = 5

• We draw a vertical line from x = 1 and see where it intersects the graph.
• The intersection is at (1, 4), so the correct equation is y = ln(x) + 4
