The last choice, do an is the x value so you would look at the x values which is -4, 6. And range is the y values so the highest y value and the lowest. Which is -5,4. So you answer is the last option
y = log(3x + 4) + 2
__________________________________________________________
Y-INTERCEPT: set x = 0
y = log(3(0) + 4) + 2
y = log(0 + 4) + 2
y = log( 4) + 2
Using calculator,
y = log( 4) + 2
y ≈ 2.60 when x = 0
__________________________________________________________
X-INTERCEPT: set y = 0
y = log(3x + 4) + 2
0 = log(3x + 4) + 2
-2 = log(3x + 4)
(it's simple. Always remember that the base is 10, even though there seems to be no "smaller number" next to log)
= 3x + 4
- 4 = 3x
[ - 4 ] /3 = x
x = -1.33 when y = 0

<h3>ANSWER: y-intercept is 2.60 and x-intercept is -1.33</h3>
The slope of this equation is -4
Answer:
26.3 m
Step-by-step explanation:
The length of a shadow of a building is 26 m. The distance from the top of the building to the tip of the shadow is 37 m. Find the height of the building.
We solve the above question using Pythagoras theorem
c² = a² + b²
Where
c = Longest part of the triangle = 37 m
a = Height of the triangle = ?
b = Length of the shadow = 26 m
Hence:
37² = a² + 26²
a² = 37² - 26²
a = √37² - 26²
a = √(693)
a = 26.324893162m
Approximately = 26.3 m
125 degrees
Explanation:
Angle GE and Angle GPE are the same angles, and it says in the question that GE is 125. Making, Angle GPE 125 as well.
