Answer:
if x=2 (r) then 2x+1=5
Step-by-step explanation:
Considering an "if and if only" type of function then the answer is A. if x=2 then 2x+1=5
The functions would be in the form of ax2+c. The axis of symmetry would be the y-axis , or x=0 , because b would be zero. Likewise, the y-intercept is not important, as any value of c will still yield a vertex at the y-intercept.

I'm assuming you're being taught how to work with negative intervals in algebra? Don't worry, that's why you're practising with temperature. Instead of asking online, try using the progress your teacher taught you. If you have notes, look back at them. Practise makes perfect :)
Answer:
0
Step-by-step explanation:
When a problem asks for the value of f(x), find the y value for the given x value. In this instance, since x = 8, y = 0.
Answer:
438.86
Step-by-step explanation:
1. 457 x 0.99 = 452.43 - Decreased by 1%
2. We need to decrease 452.43 again but this time by 3% - 452.43 x 0.97
3. This gives us an answer of 438.8571
4. Finally we need to round this to 2DP, the 7 (438.8571) rounds up so the number to the left increases. This leaves an answer of 438.86
Hope this helps :D
