For f (x)= -x + 8, what is the value of x for which f(x) = 9?

(A)

(B)

(C)

Step-by-step explanation:

we are given

(a)

we know that

any function is undefined when denominator =0

so, we can set denominator =0

and then we can solve for x

So, it does not have solution at

(b)

If g(x) is a vertical shift up 4 units from f(x)

Whenever we shift vertically upward by 'a' units , we always add 'a' to y-value

so, we get

g(x)=f(x)+4

we get

Graph:

(C)

we can set g(x)=8

and then we can solve for x

x=-1

Step-by-step explanation:

f (x)= -x + 8

Let f(x) = 9

9 = -x+8

Subtract 8 from each side

9-8 = -x+8-8

1 = -x

Multiply each side by -1

-1 = x
