Match the inequalities with their solutions i just need the equation

Which graph represents an even function?

Write the equation in logarithmic form m^x=n

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
