Please answer 4 and 5 thank you

4. The function )= 2" + 3 is reflected across the y-axis to produce the function g(x) What is the equation of the function g(x) ? O 8(x) =-2" - 3 O 8 (x) = 2-3-1+3 O 8 (x) = 2-+1 + 3 O 8(x) = -2" + 3 A 5. The function /(x) = 2" + 3 is transformed into g(x) = -h(x). What will be the range of the function g(x)? O (-00, -3) O (-00, 3 ) O All Real Numbers O ( co, 3) Pr
