Find the domain of the function expressed by the formula:
y=1/x −7

it's fraction function so when(x-7) is equal to zero the function will be undefined

to find when x-7 is equal to zero we will have to solve this equation

x-7=0

x=7

so when x is equal to 7 the function is undefined so the domain is all real numbers except 7

how am i supposed to answer

step-by-step explanation:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
