9. every day during january, joshua ran two miles. let x represent the date in january and f(x) represent the total number of miles joshua had run by the end of that date.

f(1) =

If you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?

F(x) = x2 − 9, and g(x) = x − 3 f(x) = x2 − 4x + 3, and g(x) = x − 3 f(x) = x2 + 4x − 5, and g(x) = x − 1 f(x) = x2 − 16, and g(x) = x − 4 h(x) = x + 5 arrowright h(x) = x + 3 arrowright h(x) = x + 4 arrowright h(x) = x − 1 arrowright

If x is 6, then 7x= a. 13 b. 42 c. 42x d. 76
