Answer:
Yes
Step-by-step explanation:
Yes , y=9x+1 is a function
There are two conditions for a relation to be a function.
Condition 1 :
For every value of x there must be a value existing
In this case if we take any real value of x , there will be some y defined for that value hence this condition satisfies.
Condition 2 :
No value of x should have two different values in y
In this case also , there are for every real value of x , we have an uniques value of y. Hence this condition also satisfies here.
Hence y=9x+1 is a function
D. When you do the math, the results to everything should be t=9. D is the only outlier. Therefore, D is the answer in this case.
Answer:
vertex = (3, 2 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = 2(x - 3)² + 2 ← is in vertex form
with vertex = (3, 2 )
