Svetllana [295]3 years ago
5 0

Answer:

x=-\frac{2}{3}

Step-by-step explanation:

subtract -3(2x-1)+8=15

          -8    -8

_____________

-3(2x-1)=7

divide

\frac{-3(2x-1)}{-3} =\frac{7}{3}

then simplify

2x-1=\frac{7}{3}

add both sides

2x-1+1=\frac{7}{3}+1

simplify again

2x-1+1=\frac{7}{3}+1=2x=-\frac{4}{3}

divide by 2

2x=-\frac{4}{3}

-2    -2

_________

2x÷2=1

-\frac{4}{6}divided by 2

x=-\frac{2}{3}

Find the domain and range of the function
SVEN [57.7K]

Answer:

domain: (-∞ , ∞)

range: (-∞, 2]

Step-by-step explanation:

the domain is the set of values of what the x value can be. This function is parabolic and upside down, it can have a range of x values from - infinity to positive infinity. The function is most likely y=-x^2 +2

range is the output (y values) the function can possibly have. the max is 2 and includes 2 so we use bracket for that. The smallest y value can reach towards negative infinity.
