Find the range of the function for given domain
f(x)=2x-7; (-2,-1,0,1,2)
Answers
Answer:
{-11, -9, -7, -5, -3}
Step-by-step explanation:
Put each domain value into the function to find the corresponding range value. The range is the list of all of those values.
__
range = f(domain)
= 2{-2, -1, 0, 1, 2} -7 = {-4, -2, 0, 2, 4} -7
= {-11, -9, -7, -5, -3} . . . . . the range for the given domain

If you have a lot of function values to find, a spreadsheet or calculator can be helpful.
Final answer:
By substituting values from the domain (-2, -1, 0, 1, 2) in the function f(x) = 2x - 7, we get the range as {-11, -9, -7, -5, -3}.
Explanation:
In the given function f(x) = 2x - 7, to find the range, we substitute the values from the given domain (-2,-1,0,1,2).
- For x=-2, f(-2)= 2*(-2) -7 = -4 -7 = -11.
- For x=-1, f(-1)= 2*(-1) -7 = -2 -7 = -9.
- For x=0, f(0)= 2*(0) -7 = 0 -7 = -7.
- For x=1, f(1)= 2*(1) -7 = 2 -7 = -5.
- For x=2, f(2)= 2*(2) -7 = 4 -7 = -3.
Hence, the range of the function for the given domain (-2,-1,0,1,2) is {-11, -9, -7, -5, -3}.

Answer:
First fund: $4000
second account: $2000
Step-by-step explanation:
invest x for first fund (A) and y for second fund (B)
interest for A: x * 0.05
interest for B: y * 0.09
0.05 x + 0.09 y = 380 ....(1)
x + y = 6000 ..... (2)
y = 6000 - x ....substitute y in (1)
0.05 x + 0.09 (6000 - x) = 380
0.05x + 540 - 0.09x = 380
0.04 x = 160
x = 4000
y = 6000 -4000 = 2000
check: 4000 x 0.05 + 2000 x 0.09 = 200 + 180 = 380

1. Multiply the dimensions
2. Make two smaller shapes and multiply each dimensions then add the answers together to get the final answer
First, it depends what shape it is.
To find the area of the:
square/rectangle: L x W (length times width)\
Triangle: 1/2 x b x h (One half times base times height)
Parallelogram: b x h (base times height)
Circle: x r^2 (Pi times radius to the power of 2)
Trapezoid: 1/2 x (a+b) x h (One-half times Base 1 plus Base two times height
Disclaimer: These are the areas for MOST shapes, not all.
hope this helpeed :)
