Given that a = -2 and b = 7 ,evaluate the following algebraic expression

(1) a(b2 -a)

-2(14--2)

-2*19

38.

I think this is the correct answer. Thanks

Answer is -32.

Step-by-step explanation:

a= -2

b=7

Expression: a(b2-a)

 -2(7*2--2) (Place 'a' and 'b' values)

= -2(14+2) (Solve inside the bracket)

= -28-4 (Multiply -2 with the values inside the bracket)

= -32 (ans)

Thank you!!

Hope it helps!! (^-^)

Follow me-

and mark me the brainliest !!!

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
