Hi! i really am not the best at math but if someone could me the best way they will be greatly rewarded with 98 4. use a graph to determine if the exponential function g( x) = -6 * 5^x is positive or negative and increasing or decreasing. (a) positive, increasing (b) positive, decreasing (c) negative, increasing (d) negative, decreasing 6. which of the exponential functions below has a y -intercept of 2? (a) f(x)=3^2x (b) g(x)=3^x+1 (c) h(x)=3^x+2 (d) j(x)=3*2^x
