<u>Answer:</u>
f(x) = (2x + 1)(2x − 1)
Explanation:
As we can see from the above function f(x) = 4
− 1, we need to find x-intercept, i.e., the value of x where this function's value is zero.
So let us Equate the function with zero
4 - 1 = 0 => 4 = 1 => = 1/4 => x = 
Hence we get 2 values of x, i.e., +1/2, and -1/2.
So now we need to check out the functions which are zero at this values of x, so let us substitute values of x in each and every option and see the values of functions.
Option A - f(x) = (4x + 1)(4x − 1) = 3, -3
Option B - f(x) = (2x + 1)(2x − 1) = 0
Option C - f(x) = 4(x2 + 1) = 5
Option D - f(x) = 2(x2 − 1) = -3/2
Hence answer is Option B
Answer:
y = 3/2x -5/2
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
3x- 2y = 5
Solve for y
Subtract 3x from each side
3x -3x- 2y =-3x+ 5
-2y = -3x+5
Divide by -2
-2y/-2 = -3x/-2 +5/-2
y = 3/2x -5/2

Answer:
q=4/3
Step-by-step explanation:
simplify the right side, to 5/3
5/4q=5/3
multiply 4/5 on both sides
q = 5/3*4/5
q = 4/3
