Question

1 sendo p(x)=x-4,calcule p(10)

2 sendo p(x)=2x+8, calcule p(1)

3 sendo p(x)=4x-5, calcule p(1)

4 sendo p(x)= x²+3x-10,calcule p(5)​

Answer 1

Resposta:

$1-p(10)=6\\\\2-p(1)=10\\\\3-p(1)=1\\\\4-p(5)=30$

Explicação passo a passo:

$1 - p(x)=x-4\\\\p(10)=10-4=6\\\\\\2-p(x)=2x+8\\\\p(1)=2(1)+8=2+8=10\\\\\\3-p(x)=4x-5\\\\p(1)=4(1)-5=4-5=1\\\\\\4-p(x)=x^2+3x-10\\\\p(5)=5^2+3(5)-10=25+15-10=30$
