Question

Plot 5 points

f (x) = x^2 + 2x -2

will someone explain how to solve for the plotted points

Answer 1

Just choose random values of f(x) and solve for the corresponding values of x

Answer 2

Your point would be (x,f(x)).

Do you need an example ?

Answer 3

so after i solve and get my x, my y is the number i originally started with?

Answer 4

Great

Answer 5

Try ...

Answer 6

it just erased all my work but basically i got 1,-2

Answer 7

How ?

Answer 8

well i had f(-2) = -2^2 + 2(-2) - 2

Answer 9

So, f(-2) = ?

Answer 10

4 - 4 -2 = -2
f(-2) = -2
1,-2

Answer 11

But how did you get that 1 ?

Answer 12

-2 divided by -2

Answer 13

No... no..

See the point must be (x,f(x))

You chose your x = -2 and got the corresponding value of f(x) = f(-2) = -2

So, your point should be (-2, -2)

Answer 14

aw ok i understand

Answer 15

thank you so much

Answer 16

for the help
