First you'll need to find the line of symmetry using the formula x=-b/2a. In this case, you have x=-(4/3)/(2*(-1/3))=(-4/3)/(-2/3). Then take this x value and plug it into your equation to get a y-value. This will be your vertex. Now what I like to do to get the other 2 points needed to graph the parabola is pick an x value 1 unit left of the vertex x value and another x value 1 unit right of the vertex x value. That will give you two points on either side of the vertex, and connecting the three points will create your parabola.
Answer:
d & e
Step-by-step explanation:
I'm assuming by "same side interior angle" they mean consecutive interior angles. I'll attach a document explaining what that is.
Answer:
5
Step-by-step explanation:
- (4n+5)-n/20=1
- cross multiply:(4n+5)-n=20
- 4n+5=20+n
- 4n-n=20-5
- 3n=15
- Divide both sides by coefficient of n
- n=5
we can't find the range of a function only with its domain , we must have its graph or its equation to say anything about it , with your information we are only able to say , its range has just a member.
