The inverse function is f(x) =
You can find the inverse of any function by switching the f(x) value and the x value. Then solve for the new f(x) value. The result will be your inverse function. Below is the step-by-step process for solving this one.
f(x) = 2x + 1 ---> Switch the f(x) and x values
x = 2f(x) + 1 ---> Subtract 1 from both sides
x - 1 = 2f(x) ----> Divide each side by 2.
= f(x) ---> Switch the order so that it looks like a function.
f(x) =
And that would be your inverse function.
Answer: B=1, C=2 and A =0.
Step-by-step explanation:
On a coordinate plane , a horizontal line is parallel to x-axis with 0 slope(m) .
Every horizontal line is written as y=c [∵ y= mx+c , here m=0 ]
Here value for x changes but values for y is fixed as c.
If the horizontal line passes through (-4,2), so for some point x= -4 and y=2.
So, Equation of line must be y=2, which can be written as (0)x+(1)y =2
By comparing this to Ax + By = C, we get B=1, C=2 and A =0
There are 30 boys in the competition. You can find it by first dividing 42 by 7 which is 6, then you multiply 6 by 5 to get 30.
