Whats the numbers to solve
I believe it might be “b” however im nor sure
The range is the output value or the y value.
You would work backwards to find the domain.
f(x) = 4x - 1 f(x) = 4x - 1
3 = 4x - 1 7 = 4x - 1
add 1 to both sides add 1 to both sides
4 = 4x 8 = 4x
divide both sides by 4 divide both sides by 4
x = 1 x = 2
f(x) = 4x - 1 f(x) = 4x - 1
11 = 4x - 1 15 = 4x - 1
add 1 to both sides add 1 to both sides
12 = 4x 16 = 4x
divide both sides by 4 divide both sides by 4
x = 3 x = 4
Domain { 1, 2, 3, 4}
Step-by-step explanation:
the products is the 2 parts of the segment lines are the same.
so,
5×8 = 4x
is correct (the second option).
which means
40 = 4x
x = 10
For the shown graph, let us make some notes to get the correct option.
First let us see that are the positive and what are the negative values of y's in the shown graph.
Note: The values of y's down the x-axis are negative and up the x-axis are positive.
From (-infinity to -2.7) it has negative values of y, that is less than 0 because it's down the x-axis.
From (-1 to 0.08) it also has negative values of y, that is less than 0.
Therefore, correct option is option B). f(x) < 0 over the intervals (-infinity, -2.7) and (-1 ,0.8).
