Answer:
B
Step-by-step explanation:
None of the above because it will be 3.2 or -3.2
Answer: Option D is correct.
Step-by-step explanation: An exponential function is in the form of where a is the initial value and b≠ 0 , b >1 .
Given: The function f(x) = y = ......[1]
The domain is all real numbers and the range is y > 0.
y-intercept defined as the graph crosses the y-axis.
Substitute the value of x= 0 in [1] to solve for y;
y = = 4
y-intercept = (0, 4)
End behavior:
when b =3 >1
then;
as ,
as ,
therefore, the only graph which represents the function y = is Option D
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, - 1) and (x₂, y₂ ) = (- 3, 3)
m =
= 
Since division by zero is undefined, then the slope is undefined.
This indicates the line is vertical and parallel to the y- axis
A = 1/2(4)(6.9)
A = 27.6 / 2
A = 13.8
answer
13.8 cm^2
