Graphing Exponential Function in Exercise ,sketch the graph of the function.See example 3 and 4.
Vlad [161]

Answer:

The attached image shows the graph for the given function.

Step-by-step explanation:

We are given the following function in the question:

y(x) = 2^{x-1}

We have to graph the given function.

Properties of the given function are:

  • It is an exponential function of the form y(x) = a^{x + b}
  • Here, a = 2, b = -1
  • The y-intercept of the given function is (0,0.5)
  • There is no x-intercept.
  • The domain of the given function is all real numbers.
  • The range of given function is (0,\infty)

The attached image shows the graph for the given function.

What is the slope intercept form of the equation 4x-8y=72
Masteriza [31]

Answer:

y = 1/2x - 9

General Formulas and Concepts:

<u>Alg I</u>

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

Standard Form: 4x - 8y = 72

<u>Step 2: Find slope-intercept form</u>

  1. Subtract 4x on both sides:          -8y = 72 - 4x
  2. Divide both sides by -8:               y = -9 + 1/2x
  3. Rewrite:                                         y = 1/2x - 9

How do you solve this? x - 2y = 4
valentina_108 [34]
If you want to solve for x, then
add 2y to both sides
x=2y+4
if want to solve for y
minus x both sides and divide by -2
x-2y=4
-2y=-x+4
y=1/2x-2
