Given f(x) = x² - 10x + 22, what is the domain of f?

A. X ≥ -5

B. x ≥ -3

C. X ≥ 5

D. All real numbers

What is the range of f?

A. y ≥ -5

B. y ≥ -3

C. y ≥ 5

D. All real numbers

Answer is D and B

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=

Y=21.95x+10 y=22.45x solve by substitution

Ican interpret and represent the remainder in division calculations sensibly for the context (eg 27.4 in calculating average height in cm: $27.44 if it represents an amount of money) solve the following problems. 15) the wildlife park charges $25.50 dollars per person to enter their park if the park made $15096 dollars today, how many people entered the park? 16) ms adams plus 2,230 other keen runners ran a marathon: between them they ran 94817.5km. how many km did each competitor run?
