The answer is -1. Look at the graph, when x=0, y=-1 so f(0)=-1.
<u>Answer:</u>
<h2>4. A = 1029 cm²</h2>
<u>Steps:</u>
A = (35×21)+(21+2×3.5)×21/2
A = 735 + (21+7)×21/2
A = 735 + 28×21/2
A = 735 + 588/2
A = 735 + 294
<h2>A = 1029 cm²</h2>
The first arrow goes from 0 to 3, which is 3 units.
The second arrow goes from 3 to 6, which is another 3 units.
The total units is 3 + 3 = 6
This means you have 2 different sets of 3, which can be modeled by 2 x 3.
The second choice is correct.
