you can't solve for x if there isn't a specific y value to use.

Smile, didnt you learn algebra (learned it last year, im in GEM, 2 grades ahead math)

f(X)=Y.
Hes talking about a function of a graph for some reason

x is whatever you make it

f(x) = | 7x - 10 |

f(x) is the function. x is the independent variable you manipulate to get the result y or f(x)

Oh forgot.
Find the critical number of the function.

I'm in Pre-calc. He's asking for the x-value, which cannot be determined unless y, or f(x), is a defined number. It is impossible to solve for a variable if there are two unknowns.

if x < 0
f(x) = -7x -10
else
f(x) = 7x - 10

at x = 0 is the part where the graph bends
(0, -10)

He could be asking where the line crosses the x-axis

f(x) = | 7x - 10 |

it crosses the x axis at 10/7

No, it would be around 1.5 or so

tell us what function of x is equal to then you can solve

Wait it's in absolute value sign

I forgot if you move right across the graph if you do that

So it might be 10, I'm not sure

No. Plug in 10/7 for x.

f(x) = | 7x - 10 |
f(x) = | 7(10/7) - 10 |
f(x) = | 10 - 10 |
f(x) = | 0 |
f(x) = 0
y = 0

so the point is (10/7, 0)

10/7 is 1.43 lol

I thought you said 10,7 at first and I was like O_e

But I think it might cross it at 10. If it does the same as when the -10 does in a parentheses, then it wouldn't go down it would go right

but then again I forgot if that's only if it's under a radical

So don't listen to me

Well technically 10/7 =/= 1.43 but its an approximation of it
