Answer:
20
Step-by-step explanation:
h(-7) just means that inside the x value, you replace the x with a -7.
h(-7) = |3x| - 1
h(-7) = | 3(-7)| - 1
h(-7) = | -21 | - 1
NOTE: -21 is inside |x|, those straight lines mean absolute value. No matter what, any negative number would turn into a positive one. And if it’s posititve, then it stays positive.
h(-7) = 21 - 1
h(-7) = 20
Answer:
Coldest day on record = -20°C
Step-by-step explanation:
Given:
Yesterday temperature = -4°C
Coldest day on record = 5 times than yesterday
Find:
Coldest day on record
Computation:
Coldest day on record = 5 × Yesterday temperature
Coldest day on record = 5 × (-4)
Coldest day on record = -20°C
Round to the nearest ten. Look at the ones value, it is a 0. Because 0 is less than 5, round down
913610 rounded to the nearest ten is 913610
hope this helps
Answer:
2x^2 - 7
we can plug any values of x into this The domain is All Real x.
The graph will be a parabola opening upwards with a minimum value when x = 0 and f(x) will be = -7
so the range is f(x) <= -7 or (-∞, -7]
Answer:
-1, 0 and 1
Step-by-step explanation:
Let's work through this step by step.
x goes from -2 to 2 so we will check each integer in between.
f(-2) and g(-2) is the first one. The table shows f(-2)=-8 and g(-2)=-2, so f(-2) does not equal g(-2)
Now we just keep doing this for x=-1,0,1, and 2
f(-1) = -1 and g(-1) = -1 so f(-1)=g(-1)
f(0)=0 and g(0)=0 so f(0)=g(0)
f(1)=1 and g(1)=1 so f(1)=g(1)
f(2)=8 and g(2)=2 so f(2) does not equal g(2)
So there were three xs that made f(x) = g(x). -1, 0 and 1, so those are your answers.
