Answer:
vertex:(2,-4)
Focus:(2,-
)
Axis of symmetry :x=2
Directrixt: y=-
Step-by-step explanation:
Answer:
Step-by-step explanation:
F(x)=-x+5
So
f(-4)= -(-4)+5
f(-4)= 4+5
f(-4)= 8
Only we have to substitute value of x then after simplification we will get answer..Hope this will help
False; consider as a counterexample the function <em>f</em> : ℝ→ℝ defined by

Clearly <em>f</em> approaches -3 as <em>x</em> gets closer to -2, but neither limit from either side is equal to the function's value at <em>x</em> = 2 (that is, -3 ≠ 0), so <em>f</em> is not continuous.
<em>Answer:</em>
<em>$5 for 8 pens</em>
<em></em>
<em>Step-by-step explanation:</em>
<em>0.625 times 8= 5 dollars</em>
<em>0.625 times 50= 31.25</em>
<em>which is way cheaper</em>
