f(x) = 25x + 3 ; g(x) = 15x ^ 2 - 5 if given x = 4
Answer (1)
To find the values of f(x) and g(x) when x = 4, substitute x = 4 into each function:For f(x):[tex]$\sf{f(4) = 25 \times 4 + 3 = 100 + 3 = \bold{\underline {103}}}$[/tex]For g(x):[tex]$\sf{g(4) = 15 \times (4)^2 - 5 = 15 \times 16 - 5 = 240 - 5 = \bold{\underline {235}}}$[/tex]Final answers:[tex]$\sf{\bold{ \underline {f(4) = 103}}}$[/tex][tex]$\sf{\bold{\underline{g(4) = 235}}}$[/tex]
