I don’t kno how to estimate using benchmarks but I kno the exacts answer is 13/10 or 1.3
Answer:
25 = 23
100 = X
Cross multiply and you will have:
25x = 2300
Step-by-step explanation:
The domain: D={-3;-2;-1; 1}
f(x) = -x + 4
subtitute
f(-3) = -(-3) + 4 = 3 + 4 = 7
f(-2) = -(-2) + 4 = 2 + 4 = 6
f(-1) = -(-1) + 4 = 1 + 4 = 5
f(1) = -1 + 4 = 3
Answer: The range: {3; 5; 6; 7}
