We know that Vertically Opposite Angles of two Lines Crossing each other are Equal.
From the Given Figure We can notice that x° and 128° are Vertically opposite Angles. So, they both should be Equal.
⇒ x° = 128°
I am not completely sure how to name faces, but I will name them using all four points.
Faces DCBA
Faces BFGC
Faces HGFE
Correct option D) Base of exponential function is greater than 1 , this function will exceed linear function .
<u>Step-by-step explanation:</u>
Here we have , f(x) = 0.25x + 25 and g(x) = 15(1.25)x . We need to tell As x approaches ∞, which function exceeds whom! Let's find out:
This function is a linear function with an equation of straight line , having slope and y-intercept as :
Graph for this function is attached below .
This function is an exponential function in the form of , where b>1 i.e. for rise in value of x there is exponential increase in value of y or , function .Basically Base of this exponential is greater than 1 , which makes it an increasing function ! Graph for this function is attached below .
Now , Comparing both graphs we see that as x approaches ∞ graph of exponential function is much more vertical than linear function . Since , base of exponential function is greater than 1 , this function will exceed linear function .Correct option D)
Answer:
f(1)=0; f(0)= -2; f(-1)=(-4); f(2)=2
Step-by-step explanation:
For the first four questions, f(1) means that x= 1, so you need to look at the graph, find the point where x= 1, and find the corresponding y value which is 0. You do this same process for each of the rest.
For 5 and 6: when they say f(x) = some value, this is the y value. So look at the graph: when y = 4, you can see that x = 3. When y = -6, you can see that x= -2.
