Evaluate the expression for the given values of the variables. 2a+b2 ; a = –3, b = –2 a. 4 b. –4 c. 7 d. 3.5

2a+b^2                2a +b2

2(-3) +(-2)^2          2(-3) + (-2) (2)

-6 +4                     -6 -4

-2                            -10

Either the choices are wrong or the problem is written incorrectly

step-by-step explanation:

we have

using a graphing tool

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
