)) Kathleen went to a natural science museum and bought an admission ticket that cost $21. She figured she could spend up to $19 on special exhibits to avoid spending too much in
all.
) Let x represent how much money Kathleen wanted to spend in all. Which inequality
describes the problem?
X-21 > 19
x - 21 S 19
)) Solve the inequality. Then, complete the sentence to describe the solution.
)) Kathleen wants to spend at most $
in all.

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

41*67/2=1373.5
