F(3)=-18
You just replace x for three for your equation and then use Ofer of operations to solve it.
So f(3)= 21+ 2(3)-5(3)^2
The exponent goes first: f(3)= 21+ 2(3)-5(9)
Next is multiplication: f(3)= 21+ 6-45
Now add: f(3)= 27-45
Finally subtract: f(3)= -18

Step-by-step explanation:
<h2>
</h2>
First of all multiply both sides by 5
That's
<h3>
</h3>
<u>Next divide both sides by 4</u>
That's
Subtract 7 from both sides to make m stand alone

B. y=3/2x
C. 18
My Dad helped me with this.
Firs month A
Second month 3A
Third month 3*3A = A (3^2)
Fourth month A(3^3)
Fith month A (3^4)
nth month A (3 ^ (n-1) )
That is an exponential model, because the variable (time, n) is the exponent of the formula.
