Without using your calculator, evaluate  $f\left(x\right)=3x+7$  for  $f\left(-4\right)$ . Write your NUMERIC answer (ex. not x=7 just 7)

Without using your calculator, evaluate  $g\left(x\right)=3x^2$  for  $g\left(2\right)$ . Write your NUMERIC answer (ex. not x=7 just 7)

Without using your calculator, evaluate  $h\left(x\right)=\sqrt{x-5}$  for  $h\left(41\right)$ . Write your NUMERIC answer (ex. not x=7 just 7)

Without using your calculator, evaluate  $f\left(x\right)=\frac{3x^2-5}{4x+10}$  for  $f\left(-5\right)$ . Write your NUMERIC answer (ex. not x=7 just 7)

Without using your calculator, evaluate  $g\left(x\right)=\frac{\sqrt{25-x^2}}{x}$  for  $g\left(4\right)$ . Write your FRACTION answer (ex. not x=5/8 just 5/8)

Without using your calculator, evaluate  $h\left(x\right)=30\left(1.2\right)^x$  for  $h\left(0\right)$ . Write your NUMERIC answer (ex. not x=7 just 7)

Based on the graph of the function  $y=g\left(x\right)$ , find  $g\left(-2\right)$  

Based on the graph of the function  $y=g\left(x\right)$ , find  $g\left(3\right)$  

Based on the graph of the function  $y=g\left(x\right)$ , how many values of x solve the equation  $g\left(x\right)=2$  ?

Ian invested $2500 in an investment vehicle that is guaranteed to earn 4% interest compounded yearly. The amount of money, A, in his account as a function of the number of years, t, since creating the account is given by the equation  $A\left(t\right)=2500\left(1.4\right)^t$  . Find  $A\left(10\right)$
