Question

The value of expression x(x-3) + 2 for x=1 is *​

Answer 1

Answer:

So x(x-3) + 2 is the function , which means

f(x) = x(x-3)

As you can see from this graph on Desmos, this function forms a parabola because expanding the equation by distributing gives x^2 -3x + 2

Plugging in 1 into the equation x(x-3) + 2 will give the answer

f(1) = 1(1–3) + 2 = (1–3) + 2 = -2 + 2 = 0

If you don’t like that approach, then on the graph for x=1, it shows that y = 0 at that point.

Hope this helps!
