Answer:
x=2
Step-by-step explanation:
F(x) = 2x^2 - 8x +8
Axis of symmetry lies at the x coordinate of vertex
To find x coordinate of vertex use formula

from the given f(x) , a= 2 and b = -8
Plug in all the values


x=2
So the axis of symmetry at x=2

Answer:
<h2>For 6 weeks, the height will be 15 inches</h2>
Step-by-step explanation:
Step one:
given data
the initial height of plant= 3inches
growth in inches per week =2inches per wee
Step two:
for x number of weeks, the height is expressed as

With the given growth function, we can estimate the height of the plant after any number of weeks, say x=6, that is 6 weeks, the height will be
substitute x=6 in the growth function

Divide 235/5 so 47 check by doing 47 times 5 it checks so the answer is 47
The correct answer is d. Solid line with shading on the side that includes the origin
We can tell this for two reasons. Firstly, since it is "greater than or equal to" we use a solid line. If it were just "greater than" than we would have used a dotted line.
Secondly, to tell if the origin should be shaded is by plugging in (0,0) and seeing if it is a true statement. If it is true, it is shaded.
5x + y ≥ -10
5(0) + 0 ≥ -10
0 + 0 ≥ -10
0 ≥ -10 (TRUE)
