Find the y-coordinate and the gradient at the points on the following curve corresponding to the given value of x: 1) y= (x+2) (x-4), x=3

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

can you put the picture up?
