The base of the exponential function must be a positive number, then option C. it's not possible.
In the graph, when x=0, y=3
Option B it's not posiible because when x=0→F(0)=3^0→y=1
In the graph, when x=1, y is approximately 4
Option A it's not possible because when x=0→F(0)=3*(0.4)^1=3*0.4→y=1.2
It's option D, because when x=0→F(0)=3*(1.4)^1=3*1.4→y= 4.2
Answer: OPtion D. F(x)=3*(1.4)^x
First point given: (5,4)
Y = -1/4x + b
4 = -1/4(5) + b
4 = -5/4 + b
b = 2.75
Equation: y = -1/4x + 2.75
Find three points
(5,4), (9,5), (1,3)
Plot these and draw a line
4/6
10/15
6/9
8/12
Hope these help you!!! =')
An obtuse triangle must have an angle greater than 90degrees (cannot equal 90). Therefore, A. would be the correct answer. This is because A. is the only set of angles that includes an angle greater than 90. Also, all angle measures add up to equal 180degrees.
