Question
Question(1):Show that the curve y=x^2-3x-5 passes through the point (5,5),(4,-1),(2,-7),(0,-5) and (-t,5) calculate the gradient at each pont. question(2):given a 5by5 matrices with determinant equal zero and the same determinant of its interior element equals zero question(3):A community yield #200 per annum for 5years.how much does it cost,if the current markrt interest rate is 7%?: pls with explanation

Hey, you have not even showed your attempt. I am sure you can do the first part.
You do not say if you know how to take derivatives. What is the second question?

You did not tell me if you have had any calculus. I do not like taking limits to find gradients.
putting in 5 and 4 and 2 and 0 and -t for x
and seeing what y is for each should not be too much for you.
I already passed this course. It is your turn.
