Try them and see.
For the first:
3(-3) + 0 = -9 . . . . not > -8
3(-2) + (-1) = -7 . . . is > -8 . . . . . 2) (-2, -1) is a solution
For the second:
4 - 4(-2) = 12 . . . . not ≤ -6
-2 -4(1) = -6 . . . . . is ≤ -6 . . . . . . 2. (1, -2) is a solution
Answer:
You would write it as 3 * 10^6
Step-by-step explanation:
To figure this out, look at the decimal place: you got a huge number. 3,000,000. that's the decimal place, right at the far right side. Move the decimal place until you got a number less than 10, so until the number is 3. How ever many times you had to move the decimal place (in this case six times) is the number you put as the power. So the expression is:
3 * 10^6
Answer:
step 2
Step-by-step explanation:
not really sure how to explain hope this helps
See the attached figure.
<span>f(x)=-2x−3 ⇒⇒ black graph ⇒⇒ range = R
</span>
<span>g(x)=-2|x+3|−3 ⇒⇒ red graph ⇒⇒ range = </span><span>{y∣y ≤ -3}
</span>
<span>h(x)=-2(x−4)²+3 ⇒⇒ blue graph ⇒⇒ </span><span>range = {y∣y ≤ 3}
</span>
<span>j(x)=-2x³+3x²+x−1
⇒⇒ green graph </span>⇒⇒ range = R
∴ <span>
The function which has a range of {y∣y ≤ 3} is </span><span>
h(x)=-2(x−4)²+3
