Hace 17 horas · Then we substitute this into f(x) to get f(g(x)) = 2(5 - x^2) - 4 = 10 - 2x^2 - 4 = -2x^2 + 6. Answer (b) (g ∘ f)(x) means we first apply f(x) and then apply g(x) to the result. So, we first find f(x) = 2x - 4. ... Use f(x) = 5x - 3 and g(x) = 4 - x^2 to evaluate the expression. a) (f o g)(-2) b) (g o f)(-2) 03:37.
Hace 6 días · Para calcular \ ( f (2) \) na função \ ( f (x) = 2x^2 - 5x + 3 \), basta substituir o valor de \ ( x \) por 2 na expressão da função: \ ( f (2) = 2 (2)^2 - 5 (2) + 3 \) \ ( f (2) = 2 (4) - 10 + 3 \) \ ( f (2) = 8 - 10 + 3 \) \ ( f (2) = 1 \) Portanto, o valor de \ ( f (2) \) é 1. 0. 0.
Hace 4 días · `f) ( 5x^2 - 2x + 10 )^2 = ( 3x^2 + 10x - 8 )^2` `<=> 5x^2 - 2x + 10 = 3x^2 + 10x - 8 hoặc 5x^2 - 2x + 10 = -3x^2 - 10x + 8` `<=> 2x^2 - 12x + 18 = 0 hoặc 8x^2 + 8x + 2 = 0` `<=> x^2 - 6x + 9 = 0 hoặc 4x^2 + 4x + 1 = 0` `<=> ( x - 3 )^2 = 0 hoặc ( 2x + 1 )^2 = 0`
Hace 5 días · Here we need to find the value of the given function at points $x=2$ and $x-5$. So, we’ll put x = 2 in f(x) to find f (2) and x = 5 in the f(x) to find f (5), then their addition will give us the answer.
