Find f(-3) if f(x)=x2

f(-3)=9

Step-by-step explanation:

We want to find what f(x), or y is, when x is equal to -3.

f(x)=x^2

We want to find f(-3). Therefore, we can substitute -3 in for x.

f(-3)=(-3)^2

Evaluate the exponent. -3^2 is the same as -3*-3.

f(-3)=-3*-3

f(-3)=9

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
