Answer:
B
Step-by-step explanation:
The graphs of the function and of its inverse function are always symmetrical about the line y = x.
The diagram shows the graph of the function f(x) (blue line).
The line with the equation y = x is the I quadrant bisector, so symmetrical graph to the grph of f(x) is red graph - graph of the function g(x).
Hence, correct option is B.
The answer is $2.50 because you do 145-132.50=12.5
Then you divide by 5 because that’s the difference between students then the final answer is 2.50
don't mind the dirty white board lol
Answer:
LCM and every 36 days
Step-by-step explanation:
X=-b/2a is the formula for finding the axis of symmetry
So x= -30/2(5)
X=-30/10
X=-3
Because the axis of symmetry is -3, we know where to place our line, and we also know that the parabola is open downwards, which means that the vertex will be maximum. To find the vertex, plug in your values with the axis of symmetry as a midway point. Plug that in for x and so you should have the following:
F(x)
Y(f(x) and y variables are interchangeable) =5(-3)^2-30(-3)+49
Solve for y(f(x))
5(-3)^2-30(-3)+49
(-3)^2=3^2
3^2*5+30*3+49
Multiply
3^2*5+90+49
Add numbers
3^2*5+139
9*5=45
45+139=184
Y=184
So, your vertex would be
(-3,184) and it would be maximum. From there you can plug in the rest of your table of values.
