Graph the following exponential functions and determine the y-intercept, domain, range, and
Ne4ueva [31]

The graph of the exponential function f(x) = 5(2)ˣ is as shown in the attached file.

<h3>How to draw the graph of an exponential Function?</h3>

We want to draw the graph of the exponential function;

f(x) = 5(2)ˣ

At input of x = 0, we have;

f(x) = 5(2)⁰ = 5

At input of x = 1, we have;

f(x) = 5(2)¹ = 10

At x = -1, we have;

f(x) = 5(2)⁻¹ = 2.5

At x = -2, we have;

f(x) = 5(2)⁻² = 1.25

What is the equation of a line, in Slope Intercept Form, with a slope of 1/3 and passes through the point (9, 7)?
levacccp [35]

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have the slope m=\dfrac{1}{3}\to y=\dfrac{1}{3}x+b

and point (9, 7). Substitute:

7=\dfrac{1}{3}(9)+b

7=3+b      <em>subtract 3 from both sides</em>

4=b\to b=4

Answer: y=\dfrac{1}{3}x+4
