Question

Solve the equation for x by graphing.

-2x-3=3^x+2

A. x ≈ -1.75

B. x ≈ -2.5

C. x ≈ -2.75

D. x ≈ -2

Answer 1

The given equation is

⇒-2 x-3=$3^{x}$ +2

⇒$3^{x}+2+2 x+3=0$

⇒$3^{x}+2 x+5=0$

As for x=-5/2, the term of the expression 2 x+ 5=0

But , there is no value of x , for which $3^{x}$ is equal to zero.

By graphically you can also see that there is no value of x for which the equality remains valid.

A. x ≈ -1.75

B. x ≈ -2.5

C. x ≈ -2.75

D. x ≈ -2

All the Options are incorrect.
