Answer:
The last one f(x)=(x+2)2+1 because two units to the right is positive and going up is also positive
It would be 1,200 because you just have to multiply 400 times 3 hope it helped :)
1 dozen = 12 apples.
3 apples cost 0.48, multiply that by 4 to get the price of 1 dozen.
0.48 x 4 = $1.92 per dozen.
Divide the total you can spend ( 3.84) by cost per dozen:
3.48 / 1.92 = 2
You can buy 2 dozen.
Slope = y2 - y1 / x2 - x1
= 8-4 / 3-2
= 4 / 1
= 4
