Need help please

I don’t know what to do for c

[terse osprey]

for two curves to intercept they are both equal

so let y = 41

as in replace f(x) with 41 and solve for x

[terse osprey]

btw you drew the y-axis on the wrong side of the parabola

the intercept is on the left

Thanks

I don’t get what you mean equal should I make x 41

[terse osprey]

no make y

[flint grail]

So 41= x square - six x plus 18

Then minus 41

[flint grail]

?

[terse osprey]

in simple terms you are finding the point on the graph (x,41)

usually there are 2 but the graph defines x as positive so it should only have 1

Yeh but how would I work it out
