Find the equation of the resulting graph g(x)g(x) when: (1) (a) f(x)=5x+7f(x)=5x+7 is reflected in the xx-axis. (2) (b) f(x)=2xf(x)=2^x is reflected in the yy-axis. (3) (c) f(x)=2x2+1f(x)=2x^2+1 is reflected in the xx-axis. (4) (d) f(x)=x4−2x3−3x2+5x−7f(x)=x^4-2x^3-3x^2+5x-7 is reflected in the yy-axis.
