a+=+3, if a%3E+1, then the parent function stretches in the y-direction
b=+-1 ->%28-1%2Ax+%29 means the parent function is reflected about the y-axis
and
k+=2-shifted upward k units
y=a%2Asqrt+%28b%28x-h%29%29%2Bk
Answer: y=3%2Asqrt%28-x%29%2B2
+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C+sqrt%28x%29%2C+3%2Asqrt%28-x%29%2B2%29+
