Option a is not a function because for x = 0, y = 3 and 4.
option b is a function.
option c is not a function because for x = 2, y = 1 and 8.
option d is not a function because for x = 1, y = -3 and 4
Answer:
<2 = 34degrees
Step-by-step explanation:
Find the diagram attached below:
First we need to get <1;
<1 + 74 = 180 (angle on a straight line)
<1 = 180 - 74
<1 = 106degrees
Also, <1 + <2 + 40 = 180 (sum of angle in a triangle)
106+<2 + 40 = 180
146 + <2 = 180
<2 = 180-146
<2 = 34degrees
Answer:
option C and F
Step-by-step explanation:
Given excluded value is x=-5
Excluded value are the values that makes the denominator 0
Now we check out each option and see , in which option the denominator becomes 0 when x=-5
When denominator has (x+5) then when we plug in x=-5
(x+5) becomes (-5+5) =0
So we look at the options that has factor (x+5) in the denominator
In option C we have x^2 -25
When we plug in -5 for x then it becomes (-5)^2 - 25 =0
So x=-5 makes the denominator 0
-5 is an excluded value for option C
Last option f has x+5 in the denominator
x=-5 make the denominator 0
so , -5 is an excluded value for option F

Answer:
(2, 1).
Step-by-step explanation:
f(x)=2x^2-8x+9
Find -b/2a first, it's -(-8)/2(2)=8/4=2.
Then find the y-coordinate of the vertex.
2(2)^2-8(2)+9=2(4)-16+9=8-16+9=-8+9=1
