To find the exponential function that passes through the points (-2, 1) and (0, 49), we can use the general form of an exponential function: y = ab^x.<br /><br />Using the point (0, 49), we can substitute the values of x and y into the equation to find the value of a:<br />49 = ab^0<br />49 = a(1)<br />49 = a<br /><br />Now, using the point (-2, 1), we can substitute the values of x and y into the equation to find the value of b:<br />1 = 49b^-2<br />1 = 49/b^2<br />b^2 = 49<br />b = √49<br />b = 7<br /><br />Therefore, the exponential function is y = 49(7)^x.
