If f(x) = x2 – 25 and g(x) = x – 5, what is the domain of
u
ve
x
all real values of x
all real values of x except x = 5
all real values of x except x = -5
all real values of x except x = 5 and x = -5

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
