Which of the following formats should be used for the domain of the function: f(x) = (x - 5) / (x^2 + 3x - 4)

A. x ≠ m
B. x ≥ m
C. x ≤ m
D. All Real Numbers

Based on the above choice, fill in the correct box below, leave the others blank (you will be asked to confirm you left them blank when you submit, this is ok). If you need to list several values, separate them with a comma. If you selected "All Real Numbers", leave the boxes below blank.

x ≠
x ≥
x ≤

step-by-step explanation:

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
