Exponential Models Review

Which function represents the general form of an exponential function?

• $f\left(x\right)=a\cdot b^x$

• $Ax+Bx=C$

• $f\left(x\right)=ax^2+bx+c$

Which function represents a linear function?

• $f\left(x\right)=\frac{1}{2}x^2-5$

• $f\left(x\right)=5\cdot\left(\frac{1}{2}\right)^x$

• $f\left(x\right)=\frac{1}{2}x-5$
