Answer:
It would be great if you would provide the image itself. I will totally answer your question.
Answer:
The answer to your question is:
Domain: (-∞, ∞)
Range: [10, ∞)
Step-by-step explanation:
Data
Graph y = 5x² + 3x + 10
Process
As it is suggested, let's use a graphing calculator. But we can sketch that because it is a quadratic equation, then the graph will be a parabola that opens upwards.
See the graph below.
Domain: are the possible values of the independent variable.
Range: are the reslunting values of the dependent variable.
Then
Domain : (- ∞, ∞) It is an open interval because -∞ and ∞ are
not included.
Range : [10, ∞) It is close because 10 is included.
Answer:
2x-2= -21
Step-by-step explanation:
Consider the attached figure. All the triangles shown are similar, so
CB/CA = CD/CB
30/50 = projection/30
projection = 30^2/50
projection = 18
9-5×6-2
4×6-2
24-2
=22
