f(x)=4x-1 find: a f(-1) b f(0) C f(1.5) d f(-4)

To find the values of the function $f(x) = 4x - 1$ for the given inputs, we need to substitute the values of $x$ into the function and simplify.<br /><br />a) $f(-1)$:<br />Substituting $x = -1$ into the function, we get:<br />$f(-1) = 4(-1) - 1 = -4 - 1 = -5$<br /><br />b) $f(0)$:<br />Substituting $x = 0$ into the function, we get:<br />$f(0) = 4(0) - 1 = 0 - 1 = -1$<br /><br />c) $f(1.5)$:<br />Substituting $x = 1.5$ into the function, we get:<br />$f(1.5) = 4(1.5) - 1 = 6 - 1 = 5$<br /><br />d) $f(-4)$:<br />Substituting $x = -4$ into the function, we get:<br />$f(-4) = 4(-4) - 1 = -16 - 1 = -17$<br /><br />Therefore, the answers are:<br />a) $f(-1) = -5$<br />b) $f(0) = -1$<br />c) $f(1.5) = 5$<br />d) $f(-4) = -17$
