Two points A(0, -4), B(2, -1) determine line AB.
What is the equation of the line AB?

to have more of what you want like money

step-by-step explanation:

save it by not spending on unnecessary stuff and have more

answer: 24

step-by-step explanation:

7x2=14

5x2=10

10+14=24

-23, -29, 34, -38, -45, -47, -59, 67, -78, -110, -514, 710

(a) x intercepts: -6 and 2

you can obtain these by solving the equation 0=x^2 +4x-12 using your favorite quadratic formula. but it is easy to verify -6 and 2 indeed satisfy this equation.

(b) y intercept: -12

this is obtained by setting x=0: 0^2+4*0-12 = -12

(c) the minimum value is: -16 (this is the vertex)

you can get the vertex by rewriting the equation into the form:

there is no global or local maximum as the function goes to infinity, so only in the limit sense: +infinity.
