3 f(x)=x^2-4 find: a f(2) b f(0) C f(-3) d f(0.25)

To find the values of the function \( f(x) = x^2 - 4 \) for the given inputs, we need to substitute each value into the function and simplify.<br /><br />a) \( f(2) \):<br />\[ f(2) = 2^2 - 4 = 4 - 4 = 0 \]<br /><br />b) \( f(0) \):<br />\[ f(0) = 0^2 - 4 = 0 - 4 = -4 \]<br /><br />c) \( f(-3) \):<br />\[ f(-3) = (-3)^2 - 4 = 9 - 4 = 5 \]<br /><br />d) \( f(0.25) \):<br />\[ f(0.25) = (0.25)^2 - 4 = 0.0625 - 4 = -3.9375 \]<br /><br />So, the correct answers are:<br />a) \( f(2) = 0 \)<br />b) \( f(0) = -4 \)<br />c) \( f(-3) = 5 \)<br />d) \( f(0.25) = -3.9375 \)
