Answer:

The first graph does NOT represent a function because it fails the vertical line test.  

Step-by-step explanation:

If you draw a vertical line through this graph, for x > 0, the line will intersect the graph in more than one place.  That tells you immediately that this graph does snot represent a function.

Answer/Step-by-step explanation:

Quotient is simply the ratio of the first numerator to the second numerator:

Let's \frac{x_1}{y}\;and\;\frac{x_2}{y} are two fractions in same terms.

Thus, \frac{x_1}{y}\div\frac{x_2}{y} {Divided by a fraction is equal to multiplied by its reciprocal}

=\frac{x_1}{y}\times\frac{y}{x_2}

Quotient is simply the quotient of their numerators.

Example could be:

\frac{2}{7}\div\frac{3}{7}

\frac{2}{7}\times\frac{7}3}

\frac{2}{3}

2 is first numerator and 3 is the second numerator.

What equation represents an exponential function that passes through the point (2, 80)?
Marina86 [1]

Answer:

f(x) = (4\sqrt{5})^{x}

Step-by-step explanation:

The exponential function looks like the following: f(x) = b^{x}.

If the function passes through the point (2, 80), then:

f(x) = b^{x} → 80 = b^{2}

Solving for 'b':

b = \sqrt{80} →b=4\sqrt{5}

Then, the equation of exponential function that passes through the point (2, 80) is: f(x) = (4\sqrt{5})^{x}
