What’s the answer? (I’ve tried substituting x for a number but then the formula doesn’t make sense). 52 years since I did my maths O grade and I don’t think I’ve ever had to use algebra irl. 0 Quote Link to comment Share on other sites More sharing options...

Impossible. It cannot and will not be graphed. 0 Quote Link to comment Share on other sites More sharing options...

Multiply out the brackets to get y=x2 + 8x + 15, then it's a parabola? 1 Quote Link to comment Share on other sites More sharing options...

Yeah, it all came back to me eventually, although the graphing bit was keen to establish the bits where the line broke the x and y axis which meant substituting 0 in for x and y, so y = 15 and x = -3 and -5. It all seemed a bit much. It got worse where you had to do it the other way round and get equation back to the wee brackety jobbies. 0 Quote Link to comment Share on other sites More sharing options...
