Since both are equivalent to f(x), 4x-7 must equal 8
4x-7=8
Add 7 to both sides
4x= 15
Divide both sides by 4
x=15/4
Final answer: x=15/4
The answer is the fourth graph.
So what makes a function a function is that every input (x) has only one output (y). To test if a line is a function on a graph, you would use something called the "vertical line test". Move a vertical line across the graph, and if at any point there was more than one point on the vertical line it would not be considered a function. And the only graph that has no more than one point when moving a vertical line across the graph is the last graph.
Answer:
-2
Step-by-step explanation:
-4x^3 = 32
x^3 = -8
take the cube root of both sides.
x = -2
Multiply:
1.17 x 1.5 = 1.755
rounded to 2 places = 1.76 minutes
